Security Bulletin

This security bulletin contains one high risk vulnerability.

1) Security features bypass

EUVDB-ID: #VU85991

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C]

CVE-ID: CVE-2024-21626

CWE-ID: CWE-254 - Security Features

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to an internal file descriptor leak that can cause a newly-spawned container process (from runc exec) to have a working directory in the host filesystem namespace or a malicious image to allow a container process to gain access to the host filesystem through runc run. A remote attacker can trick the victim into loading a malicious image to bypass sandbox restrictions and execute arbitrary code on the host OS.

Mitigation

Install updates from vendor's website.
