NewCVE-2024-48991 (opens in a new tab)How to fix?
Upgrade Ubuntu:24.10 needrestart to version 3.6-8ubuntu4.2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream needrestart package and not the needrestart package as distributed by Ubuntu.
See How to fix? for Ubuntu:24.10 relevant fixed versions and status.
Qualys discovered that needrestart, before version 3.8, allows local attackers to execute arbitrary code as root by winning a race condition and tricking needrestart into running their own, fake Python interpreter (instead of the system's real Python interpreter). The initial security fix (6ce6136) introduced a regression which was subsequently resolved (42af5d3).
