CWE-59  (opens in a new tab)

How to fix?

Upgrade SLES:15.0 permissions to version 20180125-3.18.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream permissions package and not the permissions package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

The chkstat tool in the permissions package followed symlinks before commit a9e1d26cd49ef9ee0c2060c859321128a6dd4230 (please also check the additional hardenings after this fix). This allowed local attackers with control over a path that is traversed by chkstat to escalate privileges.
