USN-6601-1: Linux kernel vulnerability
25 January 2024
The system could be made to crash or run programs as an administrator.
Releases
Packages
- linux - Linux kernel
Details
It was discovered that the IGMP protocol implementation in the Linux kernel
contained a race condition, leading to a use-after-free vulnerability. A
local attacker could use this to 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 14.04
-
linux-image-3.13.0-195-generic
-
3.13.0-195.246
Available with Ubuntu Pro
-
linux-image-3.13.0-195-lowlatency
-
3.13.0-195.246
Available with Ubuntu Pro
-
linux-image-generic
-
3.13.0.195.205
Available with Ubuntu Pro
-
linux-image-generic-lts-trusty
-
3.13.0.195.205
Available with Ubuntu Pro
-
linux-image-lowlatency
-
3.13.0.195.205
Available with Ubuntu Pro
-
linux-image-server
-
3.13.0.195.205
Available with Ubuntu Pro
-
linux-image-virtual
-
3.13.0.195.205
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.
