## How to fix

- Fixed in GPAC 2.5

## Technical details

A segmentation violation exists in the gf_props_equal_internal function within filter_core/filter_props.c when comparing PID property values. The vulnerability is triggered by supplying crafted media data containing malformed descriptors or property structures, leading to a read-access fault. An attacker can exploit this via a specially constructed MP4 file to cause a denial-of-service condition.

## Affected products

- GPAC Project MP4Box before 2.5

## Timeline

- 2025-09-03: disclosed
- 2026-10-20: advisory
- patched: Fix prevents const data properties from being passed as user-assigned PID properties
