Description

This security bulletin contains information about 1 security vulnerability.


1) Input validation error (CVE-ID: CVE-2025-1390)

The vulnerability allows a local user to bypass implemented security restrictions.

The vulnerability exists due to insufficient validation of user-supplied input when parsing groups names. The PAM module pam_cap.so of libcap configuration supports group names starting with “@”, during actual parsing, configurations not starting with “@” are incorrectly recognized as group names. A local user can use this vulnerability to escalate privileges on systems where "/etc/security/capability.conf" is used to configure user inherited privileges by constructing specific usernames.
