Ubuntu Security Notice USN-1883-1
June 14, 2013
linux-ti-omap4 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.04
Summary:
Several security issues were fixed in the kernel.
Software Description:
- linux-ti-omap4: Linux kernel for OMAP4
Details:
Kees Cook discovered a flaw in the Linux kernel's iSCSI subsystem. A remote
unauthenticated attacker could exploit this flaw to cause a denial of
service (system crash) or potentially gain administrative privileges.
(CVE-2013-2850)
An information leak was discovered in the Linux kernel's crypto API. A
local user could exploit this flaw to examine potentially sensitive
information from the kernel's stack memory. (CVE-2013-3076)
An information leak was discovered in the Linux kernel's rcvmsg path for
ATM (Asynchronous Transfer Mode). A local user could exploit this flaw to
examine potentially sensitive information from the kernel's stack memory.
(CVE-2013-3222)
An information leak was discovered in the Linux kernel's recvmsg path for
ax25 address family. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3223)
An information leak was discovered in the Linux kernel's recvmsg path for
the bluetooth address family. A local user could exploit this flaw to
examine potentially sensitive information from the kernel's stack memory.
(CVE-2013-3224)
An information leak was discovered in the Linux kernel's bluetooth rfcomm
protocol support. A local user could exploit this flaw to examine
potentially sensitive information from the kernel's stack memory.
(CVE-2013-3225)
An information leak was discovered in the Linux kernel's Rose X.25 protocol
layer. A local user could exploit this flaw to examine potentially
sensitive information from the kernel's stack memory. (CVE-2013-3234)
An information leak was discovered in the Linux kernel's TIPC (Transparent
Inter Process Communication) protocol implementation. A local user could
exploit this flaw to examine potentially sensitive information from the
kernel's stack memory. (CVE-2013-3235)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 13.04:
linux-image-3.5.0-226-omap4 3.5.0-226.39
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
