Description

This security bulletin contains information about 1 vulnerability.


1) Path traversal (CVE-ID: CVE-2023-35936)

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

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a local user to create or overwrite arbitrary files on the system.

The vulnerability exists due to improper path restriction in media extraction handling when processing a specially crafted image element in untrusted input during PDF generation or when using the --extract-media option. A local user can supply crafted input with a percent-encoded path in a media URI to create or overwrite arbitrary files on the system.

User interaction is required to process untrusted input, and only configurations that generate PDF output or use the --extract-media option are affected.
