Details

USN-5811-1 fixed a vulnerability in Sudo. This update provides
the corresponding update for Ubuntu 16.04 ESM.

Original advisory details:

Matthieu Barjole and Victor Cutillas discovered that Sudo incorrectly
handled user-specified editors when using the sudoedit command. A local
attacker that has permission to use the sudoedit command could possibly use
this issue to edit arbitrary files. (CVE-2023-22809)
