USN-5478-1: util-linux vulnerability

14 June 2022

A util-linux program could be made to crash if it opened a specially crafted file system.




Christian Moch and Michael Gruhn discovered that the libblkid library
of util-linux did not properly manage memory under certain
circumstances. A local attacker could possibly use this issue
to cause denial of service by consuming all memory through
a specially crafted MSDOS partition table.

Update instructions

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

Ubuntu 16.04

In general, a standard system update will make all the necessary changes.
