USN-5334-1: man-db vulnerability
17 March 2022
man-db could be made to overwrite file and directory permissions.
Releases
Packages
- man-db - on-line manual pager
Details
It was discovered that man-db incorrectly handled permission changing
operations in its daily cron job, and was therefore affected by a race
condition. An attacker could possibly use this issue to escalate privileges
and execute arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04
-
man-db
-
2.7.5-1ubuntu0.1~esm1
Available with Ubuntu Pro
In general, a standard system update will make all the necessary changes.
