Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Security features bypass
EUVDB-ID: #VU85991
Risk: High
CVSSv4.0: 7.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Amber]
CVE-ID: CVE-2024-21626
CWE-ID:
CWE-254 - Security Features
Exploit availability: Yes
DescriptionThe 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.
