Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Path traversal

EUVDB-ID: #VU60001

Risk: Medium

CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-22815

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: No

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 in path_getbbox() function in path.c. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system.

Mitigation

Install updates from vendor's repository.
