Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) UNIX symbolic link following
EUVDB-ID: #VU118104
Risk: Low
CVSSv4.0: 6.4 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2025-31133
CWE-ID:
CWE-61 - UNIX Symbolic Link (Symlink) Following
Exploit availability: Yes
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a symlink following issue within the maskedPaths feature. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.
Successful exploitation of this vulnerability may result in privilege escalation.
MitigationUpdate the affected package runc to the latest version.
