Ubuntu Security Notice USN-7298-1
February 25, 2025
linux, linux-lts-xenial vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
Summary:
The system could be made to crash or run programs as an administrator.
Software Description:
- linux: Linux kernel
- linux-lts-xenial: Linux hardware enablement kernel from Xenial for Trusty
Details:
Attila Szász discovered that the HFS+ file system implementation in the
Linux Kernel contained a heap overflow vulnerability. An attacker could use
a specially crafted file system image that, when mounted, could cause a
denial of service (system crash) or possibly execute arbitrary code.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 16.04 LTS
linux-image-4.4.0-264-generic 4.4.0-264.298
Available with Ubuntu Pro
linux-image-4.4.0-264-lowlatency 4.4.0-264.298
Available with Ubuntu Pro
linux-image-generic 4.4.0.264.270
Available with Ubuntu Pro
linux-image-generic-lts-xenial 4.4.0.264.270
Available with Ubuntu Pro
linux-image-lowlatency 4.4.0.264.270
Available with Ubuntu Pro
linux-image-virtual 4.4.0.264.270
Available with Ubuntu Pro
Ubuntu 14.04 LTS
linux-image-4.4.0-264-generic 4.4.0-264.298~14.04.1
Available with Ubuntu Pro
linux-image-4.4.0-264-lowlatency 4.4.0-264.298~14.04.1
Available with Ubuntu Pro
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.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
