ubuntu
Calendar Grey August 30, 2022
Dist Ubuntu Esm H88
The latest Ubuntu Security Advisory USN-5588-1 addresses a vulnerability in the kernel that could lead to system instability or enable execution of privileged commands by unauthorized users.
The system could be made to crash or run programs as an administrator.

Summary

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

Software Description:

- linux: Linux kernel

Details:

Zhenpeng Lin discovered that the network packet scheduler implementation

in the Linux kernel did not properly remove all references to a route

filter before freeing it in some situations. A local attacker could use

this to cause a denial of service (system crash) or execute arbitrary code.

Update Instructions

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 ESM:
   linux-image-3.13.0-191-generic  3.13.0-191.242
   linux-image-3.13.0-191-lowlatency  3.13.0-191.242
   linux-image-generic             3.13.0.191.201
   linux-image-lowlatency          3.13.0.191.201
   linux-image-server              3.13.0.191.201
   linux-image-virtual             3.13.0.191.201

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.
