Security Bulletin
This security bulletin contains one low risk vulnerability.
1) Input validation error
EUVDB-ID: #VU104166
Risk: Low
CVSSv4.0: 5.9 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2025-1390
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe 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.
MitigationInstall updates from vendor's repository.
