[lfs-announce] Linux From Scratch 11.0-rc3 Released
The Linux From Scratch community announces the release of LFS Version
11.0-rc3. It is a preliminary release of LFS-11.0.
This version of the Linux From Scratch book has been released due to a
critical security vulnerability in openssl. This vulnerability has been
fixed in LFS 11.0-rc3 by updating to the latest version: openssl-1.1.1l
(version 1.1.1 lower case L). Usage of LFS 11.0-rc1 or LFS 11.0-rc2 is
deemed unsafe and insecure.
In addition to the above, we took the opportunity to update several
other packages from the recent -rc releases to the latest stable
versions: e2fsprogs, meson, the linux kernel, util-linux, and libcap.
You can read the book online [0], or download [1] to read locally.
In coordination with this release, a new version of LFS using the
systemd package is also being released. This package implements the
newer systemd style of system initialization and control and is
consistent with LFS in most packages.
You can read the systemd version of the book online [2], or download [3]
to read locally.
Please direct any comments about this release to the LFS development
team at lfs-dev@lists.linuxfromscratch.org. Please note that
registration for the lfs-dev mailing list is required to avoid junk email.

[FreeBSD-Announce] FreeBSD Security Advisory FreeBSD-SA-21:17.openssl
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
=============================================================================
FreeBSD-SA-21:17.openssl Security Advisory
The FreeBSD Project
Topic: Multiple vulnerabilities in OpenSSL
Category: contrib
Module: openssl
Announced: 2021-08-24
Affects: FreeBSD 12.2 and FreeBSD 11.4
Corrected: 2021-02-18 23:55:09 UTC (stable/12, 12.2-STABLE)
2021-08-24 18:32:22 UTC (releng/12.2, 12.2-RELEASE-p10)
2021-02-19 16:21:03 UTC (stable/11, 11.4-STABLE)
2021-08-24 18:31:34 UTC (releng/11.4, 11.4-RELEASE-p13)
CVE Name: CVE-2021-23840, CVE-2021-23841
For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:https://security.FreeBSD.org/>.
I. Background
FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is a
collaborative effort to develop a robust, commercial-grade, full-featured
Open Source toolkit for the Transport Layer Security (TLS) protocol. It is
also a general-purpose cryptography library.
II. Problem Description
This advisory covers two distinct OpenSSL issues:
Calls to EVP_CipherUpdate(), EVP_EncryptUpdate() and EVP_DecryptUpdate()
may overflow the output length argument in some cases where the input
length is close to the maximum permissable length for an integer on the
platform. In such cases the return value from the function call will be
1 (indicating success), but the output length value will be negative.
[CVE-2021-23840]
The OpenSSL public API function X509_issuer_and_serial_hash() attempts
to create a unique hash value based on the issuer and serial number data
contained within an X509 certificate. However it fails to correctly
handle any errors that may occur while parsing the issuer field (which
might occur if the issuer field is maliciously constructed).
[CVE-2021-23841]
III. Impact
The integer overflow in EVP_*Update() could cause applications to behave
incorrectly or crash leading to a potential denial of service attack.
The X509_issuer_and_serial_hash() issue may result in a NULL pointer
dereference and a crash leading to a potential denial of service attack.
IV. Workaround
No workaround is available.
The function X509_issuer_and_serial_hash() is never directly called by
OpenSSL itself so applications are only vulnerable if they use this
function directly and they use it on certificates that may have been
obtained from untrusted sources.
V. Solution
Upgrade your vulnerable system to a supported FreeBSD stable or

FreeBSD-SA-21:17.openssl Security Advisory
The FreeBSD Project
Topic: Multiple vulnerabilities in OpenSSL
Category: contrib
Module: openssl
Announced: 2021-08-24
Affects: FreeBSD 12.2 and FreeBSD 11.4
Corrected: 2021-02-18 23:55:09 UTC (stable/12, 12.2-STABLE)
2021-08-24 18:32:22 UTC (releng/12.2, 12.2-RELEASE-p10)
2021-02-19 16:21:03 UTC (stable/11, 11.4-STABLE)
2021-08-24 18:31:34 UTC (releng/11.4, 11.4-RELEASE-p13)
CVE Name: CVE-2021-23840, CVE-2021-23841
For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:https://security.FreeBSD.org/>.
I. Background
FreeBSD includes software from the OpenSSL Project. The OpenSSL Project is a
collaborative effort to develop a robust, commercial-grade, full-featured
Open Source toolkit for the Transport Layer Security (TLS) protocol. It is
also a general-purpose cryptography library.
II. Problem Description
This advisory covers two distinct OpenSSL issues:
Calls to EVP_CipherUpdate(), EVP_EncryptUpdate() and EVP_DecryptUpdate()
may overflow the output length argument in some cases where the input
length is close to the maximum permissable length for an integer on the
platform. In such cases the return value from the function call will be
1 (indicating success), but the output length value will be negative.
[CVE-2021-23840]
The OpenSSL public API function X509_issuer_and_serial_hash() attempts
to create a unique hash value based on the issuer and serial number data
contained within an X509 certificate. However it fails to correctly
handle any errors that may occur while parsing the issuer field (which
might occur if the issuer field is maliciously constructed).
[CVE-2021-23841]
III. Impact
The integer overflow in EVP_*Update() could cause applications to behave
incorrectly or crash leading to a potential denial of service attack.
The X509_issuer_and_serial_hash() issue may result in a NULL pointer
dereference and a crash leading to a potential denial of service attack.
IV. Workaround
No workaround is available.
The function X509_issuer_and_serial_hash() is never directly called by
OpenSSL itself so applications are only vulnerable if they use this
function directly and they use it on certificates that may have been
obtained from untrusted sources.
V. Solution
Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date.
Perform one of the following:
1) To update your vulnerable system via a binary patch:
Systems running a RELEASE version of FreeBSD on the amd64, i386, or
(on FreeBSD 13 and later) arm64 platforms can be updated via the
freebsd-update(8) utility:
# freebsd-update fetch
# freebsd-update install
2) To update your vulnerable system via a source code patch:
The following patches have been verified to apply to the applicable
FreeBSD release branches.
a) Download the relevant patch from the location below, and verify the
detached PGP signature using your PGP utility.

2021-08-24 18:31:29 UTC (releng/11.4, 11.4-RELEASE-p13)
CVE Name: CVE-2021-29630
For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:https://security.FreeBSD.org/>.
I. Background
GEOM Gate is a GEOM module that reflects I/O requests into user mode where
the ggatec(8) daemon fowards those requests to ggated(8), possibly over the
network to another machine.
II. Problem Description
The ggatec(8) daemon does not validate the size of a response before writing
it to a fixed-sized buffer. This allows to overwrite the stack of ggatec(8).
III. Impact
A malicious ggated(8) or an attacker in a priviledged network position can
overwrite the stack with crafted content and potentially execute arbitrary
code.
IV. Workaround
No workaround is available but systems not using ggatec(8) are not affected.
Neither ggatec(8) nor ggated(8) are enabled by default and need explicit
configuration by the super-user.
V. Solution
Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date.
Restart any ggatec(8) instances. Existing ggate devices can be kept alive
and restarted with `ggatec rescue`.
Perform one of the following:
1) To update your vulnerable system via a binary patch:
Systems running a RELEASE version of FreeBSD on the amd64, i386, or
(on FreeBSD 13 and later) arm64 platforms can be updated via the
freebsd-update(8) utility:
# freebsd-update fetch
# freebsd-update install
2) To update your vulnerable system via a source code patch:
The following patches have been verified to apply to the applicable
FreeBSD release branches.
a) Download the relevant patch from the location below, and verify the
detached PGP signature using your PGP utility.
# fetch https://security.FreeBSD.org/patches/SA-21:14/ggatec.patch
# fetch https://security.FreeBSD.org/patches/SA-21:14/ggatec.patch.asc
# gpg --verify ggatec.patch.asc
b) Apply the patch. Execute the following commands as root:
# cd /usr/src
# patch < /path/to/patch
c) Recompile the operating system using buildworld and installworld as
described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>.
Restart the applicable daemons, or reboot the system.

Topic: Missing error handling in bhyve(8) device models
Category: core
Module: bhyve
Announced: 2021-08-24
Credits: Agustin Gianni (GitHub Security Lab)
Affects: All supported versions of FreeBSD.
Corrected: 2021-08-24 18:29:48 UTC (stable/13, 13.0-STABLE)
2021-08-24 17:33:35 UTC (releng/13.0, 13.0-RELEASE-p4)

2021-08-24 18:31:27 UTC (releng/11.4, 11.4-RELEASE-p13)
CVE Name: CVE-2021-29631
For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:https://security.FreeBSD.org/>.
I. Background
bhyve(8) is a hypervisor that supports running a variety of guest
operating systems in virtual machines. It implements a number of device
models using the VirtIO interface to exchange data between the guest and
the host.
II. Problem Description
Certain VirtIO-based device models failed to handle errors when fetching
I/O descriptors. Such errors could be triggered by a malicious guest.
As a result, the device model code could be tricked into operating on
uninitialized I/O vectors, leading to memory corruption.
III. Impact
A malicious guest may be able to crash the bhyve process. It may be
possible to exploit the memory corruption bugs to achieve arbitrary code
execution in the bhyve process.
IV. Workaround
No workaround is available. Virtual machines are unaffected unless they
use one or more of the following device models:
* virtio-console
* virtio-rnd
* virtio-scsi (available starting in FreeBSD 12.0)
* virtio-9p (available starting in FreeBSD 13.0)
V. Solution
Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date.
Perform one of the following:
1) To update your vulnerable system via a binary patch:
Systems running a RELEASE version of FreeBSD on the amd64, i386, or

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
=============================================================================
FreeBSD-SA-21:15.libfetch Security Advisory
The FreeBSD Project
Topic: libfetch out of bounds read
Category: core
Module: libfetch
Announced: 2021-08-24
Credits: Samanta Navarro
Affects: All supported versions of FreeBSD.
Corrected: 2021-08-24 17:59:43 UTC (stable/13, 13.0-STABLE)
2021-08-24 18:00:47 UTC (releng/13.0, 13.0-RELEASE-p4)
2021-08-24 18:30:16 UTC (stable/12, 12.2-STABLE)
2021-08-24 18:32:17 UTC (releng/12.2, 12.2-RELEASE-p10)
2021-08-24 18:29:40 UTC (stable/11, 11.4-STABLE)
2021-08-24 18:31:31 UTC (releng/11.4, 11.4-RELEASE-p13)
CVE Name: CVE-2021-36159
For general information regarding FreeBSD Security Advisories,
including descriptions of the fields above, security branches, and the
following sections, please visit <URL:https://security.FreeBSD.org/>.
I. Background
libfetch(3) is a multi-protocol file transfer library included with FreeBSD
and used by the fetch(1) command-line tool, pkg(8) package manager, and
others.
II. Problem Description
The passive mode in FTP communication allows an out of boundary read while
libfetch uses strtol to parse the relevant numbers into address bytes. It
does not check if the line ends prematurely. If it does, the for-loop
condition checks for *p == '\0' one byte too late because p++ was already
performed.
III. Impact
The connection buffer size can be controlled by a malicious FTP server
because the size is increased until a newline is encountered (or no more
characters are read). This also allows to move the buffer into more
interesting areas within the address space, potentially parsing relevant
numbers for the attacker. Since these bytes become available to the server
in form of a new TCP connection to a constructed port number or even part of
the IPv6 address this is a potential information leak.
IV. Workaround
No workaround is available.
V. Solution
Upgrade your vulnerable system to a supported FreeBSD stable or
release / security branch (releng) dated after the correction date.
Perform one of the following:
1) To update your vulnerable system via a binary patch:
Systems running a RELEASE version of FreeBSD on the amd64, i386, or
(on FreeBSD 13 and later) arm64 platforms can be updated via the
freebsd-update(8) utility:
# freebsd-update fetch
# freebsd-update install
2) To update your vulnerable system via a source code patch:
The following patches have been verified to apply to the applicable
FreeBSD release branches.
a) Download the relevant patch from the location below, and verify the
detached PGP signature using your PGP utility.
# fetch https://security.FreeBSD.org/patches/SA-21:15/libfetch.patch
# fetch https://security.FreeBSD.org/patches/SA-21:15/libfetch.patch.asc
# gpg --verify libfetch.patch.asc
b) Apply the patch. Execute the following commands as root:
# cd /usr/src
# patch < /path/to/patch
c) Recompile the operating system using buildworld and installworld as
described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>.

FreeBSD-EN-21:25.bhyve Errata Notice
The FreeBSD Project
Topic: Fix NVMe iovec construction for large IOs
Category: core
Module: bhyve
Announced: 2021-08-24
Affects: FreeBSD 12.2 and later.
Corrected: 2021-07-09 14:24:14 UTC (stable/13, 13.0-STABLE)
2021-08-24 17:25:47 UTC (releng/13.0, 13.0-RELEASE-p4)

2021-08-24 18:32:11 UTC (releng/12.2, 12.2-RELEASE-p10)
For general information regarding FreeBSD Errata Notices and Security
Advisories, including descriptions of the fields above, security
branches, and the following sections, please visit
<URL:https://security.FreeBSD.org/>.
I. Background
bhyve(8) is a hypervisor that supports running a variety of guest
operating systems in virtual machines. Newer UEFI code in Red Hat
Enterprise Linux (RHEL) 8.4 and later (as well as applicable variants)
will not boot in newly installed guests.
II. Problem Description
By default, NVMe data transfer operations use a scatter-gather list in
which all entries point to a fixed-size memory region. For example, if
the memory page size is 4KB, a 2MB IO requires 512 entries. Lists
themselves are also fixed in size (default is 512 entries).
Because the list size is fixed, the last entry is special. If the IO
requires more than 512 entries, the last entry in the list contains the
address of the next list of entries. But if the IO requires exactly 512
entries, the last entry points to data.
The NVMe emulation missed this logic and unconditionally treated the
last entry as a pointer to the next list.
III. Impact
When a RHEL 8.4 and later (or variants) are installed as guests within
bhyve(8) on emulated NVMe storage, the system will not boot due to a
newer UEFI driver that is included with these distributions.
IV. Workaround
Installation of a RHEL 8.3 guest and performing an in-place upgrade.
V. Solution
Upgrade your system to a supported FreeBSD stable or release / security
branch (releng) dated after the correction date.
Perform one of the following:
1) To update your system via a binary patch:
Systems running a RELEASE version of FreeBSD on the amd64, i386, or
(on FreeBSD 13 and later) arm64 platforms can be updated via the

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512
=============================================================================
FreeBSD-EN-21:24.libcrypto Errata Notice
The FreeBSD Project
Topic: OpenSSL 1.1.1e API functions not exported
Category: core
Module: libcrypto
Announced: 2021-08-24
Affects: FreeBSD 12.2 and later.
Corrected: 2021-06-09 21:53:42 UTC (stable/13, 13.0-STABLE)
2021-08-24 17:25:47 UTC (releng/13.0, 13.0-RELEASE-p4)
2021-06-09 21:54:13 UTC (stable/12, 12.2-STABLE)
2021-08-24 18:32:08 UTC (releng/12.2, 12.2-RELEASE-p10)
For general information regarding FreeBSD Errata Notices and Security
Advisories, including descriptions of the fields above, security
branches, and the following sections, please visit
<URL:https://security.FreeBSD.org/>.
I. Background
libcrypto is part of the OpenSSL distribution and provides APIs to
various low-level cryptographic services.
II. Problem Description
New API functions added in OpenSSL 1.1.1e and later were not publicly
exported to applications.
III. Impact
Applications trying to use new API functions added in OpenSSL 1.1.1e
or later would fail to build with a link error.
IV. Workaround
No workaround is available. However, the APIs added in OpenSSL 1.1.1e
and later are obscure and not used by many applications. In particular,
none of the affected APIs are used by applications using libssl from
OpenSSL for Transport Layer Security (TLS).
V. Solution
Upgrade your system to a supported FreeBSD stable or release / security
branch (releng) dated after the correction date.
Perform one of the following:
1) To update your system via a binary patch:
Systems running a RELEASE version of FreeBSD on the amd64, i386, or
(on FreeBSD 13 and later) arm64 platforms can be updated via the
freebsd-update(8) utility:
# freebsd-update fetch
# freebsd-update install
2) To update your system via a source code patch:
The following patches have been verified to apply to the applicable
FreeBSD release branches.
a) Download the relevant patch from the location below, and verify the
detached PGP signature using your PGP utility.
# fetch https://security.FreeBSD.org/patches/EN-21:17/libcrypto.patch
# fetch https://security.FreeBSD.org/patches/EN-21:17/libcrypto.patch.asc
# gpg --verify libcrypto.patch.asc
b) Apply the patch. Execute the following commands as root:
# cd /usr/src
# patch < /path/to/patch
c) Recompile the operating system using buildworld and installworld as
described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>.
