CVE-2025-60478 · Severity: info · Published 2026-10-21

GPAC's MP4Box is a multimedia file processor used to convert and package video and audio content. A use-after-free vulnerability in packet memory management allows attackers to crash the application and cause a denial of service by supplying a crafted MPEG-2 file with malformed program tables. The issue occurs when processing malformed DASH segments.

## How to fix

- Fixed in 2.5

## Technical details

A use-after-free flaw exists in the gf_filter_packet_destroy function (filter_core/filter_pck.c:678) triggered when processing MPEG-2 TS files with malformed PMT/PAT tables and empty DASH segments. The vulnerability stems from improper packet memory lifetime management in the filter pipeline. The fix verifies the nb_shared_packets_out counter before destroying filters to prevent freeing packets that are still in use.

## Affected products
