CVE-2022-31250

Root escalation via symlink-following %post scriptlet

Published Jul 20, 2022 · Updated Sep 17, 2024

Improper link resolution in keylime on OpenSUSE openSUSE Tumbleweed before 6.4.2-1.1 allows local attackers to gain root via package installation. The keylime RPM %post scriptlet follows attacker-controlled symbolic links while changing ownership or permissions, allowing the keylime account to redirect an operation onto root-owned files. Exploitation requires local access as the keylime user; successful abuse can compromise confidentiality, integrity, and availability.
