This security bulletin contains information about 2 vulnerabilities.

1) Path traversal

EUVDB-ID: #VU26643

Risk: High

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

Description

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences. A remote attacker can trick a victim to build a malicious container image hosted on an HTTP(s) server and then write files to the user's system anywhere that the user has permissions.

Mitigation

Update the affected package buildah to the latest version.
