========================================================================== 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.
