USN-5447-1: logrotate vulnerability

26 May 2022

logrotate could be made to stop processing log files.




It was discovered that logrotate incorrectly handled the state file. A
local attacker could possibly use this issue to keep a lock on the state
file and cause logrotate to stop working, leading to a denial of service.

Update instructions

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

Ubuntu 22.04
Ubuntu 21.10

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