Ubuntu Security Notice USN-6601-1
January 25, 2024

linux vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS (Available with Ubuntu Pro)

Summary:

The system could be made to crash or run programs as an administrator.

Software Description:
- 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 LTS (Available with Ubuntu Pro):
linux-image-3.13.0-195-generic 3.13.0-195.246
linux-image-3.13.0-195-lowlatency 3.13.0-195.246
linux-image-generic 3.13.0.195.205
linux-image-generic-lts-trusty 3.13.0.195.205
linux-image-lowlatency 3.13.0.195.205
linux-image-server 3.13.0.195.205
linux-image-virtual 3.13.0.195.205

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.
