Ubuntu Security Notice USN-4512-1
September 17, 2020

util-linux vulnerability
==========================================================================

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

– Ubuntu 18.04 LTS

Summary:

util-linux could be made to run programs when performing bash completion.

Software Description:
– util-linux: miscellaneous system utilities

Details:

It was discovered that the umount bash completion script shipped in
util-linux incorrectly handled certain mountpoints. If a local attacker
were able to create arbitrary mountpoints, another user could be tricked
into executing arbitrary code when attempting to run the umount command
with bash completion.

Update instructions:

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

Ubuntu 18.04 LTS:
util-linux 2.31.1-0.4ubuntu3.7

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