Description

This security bulletin contains information about 1 vulnerability.


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

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.
