Publication date: 2026-09-13

Last updated on: 2026-09-13

Assigner: VulDB

Description
A vulnerability was detected in GPAC up to f1219cde. Affected by this vulnerability is the function gf_node_get_field of the file scenegraph/base_scenegraph.c of the component MP4Box. Performing a manipulation results in heap-based buffer overflow. The attack is only possible with local access. The exploit is now public and may be used. Upgrading to version abi-16.23 addresses this issue. The patch is named 49dee5cad329cfed310c1682703df7daa47df31a. The affected component should be upgraded.

CWE ID Description
CWE-122 A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
CWE-119 The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

Executive Summary

CVE-2026-90577 is a heap-based buffer overflow vulnerability in GPAC's MP4Box tool. It occurs in the gf_node_get_field function when processing a crafted MP4 file with the -nstatx option. The issue involves a recursive call in StatNodeGraph that attempts to unregister a node whose memory is already freed or out of bounds, leading to an 8-byte read past the end of the object. This can cause information disclosure or a denial of service via process crash.

Detection Guidance

To detect this vulnerability, monitor for crashes or AddressSanitizer errors when processing MP4 files with the MP4Box -nstatx command. Check for heap-buffer-overflow errors in logs or during fuzzing tests.

Impact Analysis

This vulnerability allows attackers with local access to trigger a heap-based buffer overflow. This could lead to information disclosure by reading sensitive memory or cause a denial of service by crashing the MP4Box process. Exploitation requires crafting a specific MP4 file and using the -nstatx command.

Compliance Impact

This vulnerability is a heap-based buffer overflow in GPAC's MP4Box tool, enabling potential information disclosure or denial of service. Such issues could violate GDPR's integrity principle (Article 5) or HIPAA's security rule (45 CFR 164.308) by compromising data integrity or availability, though direct compliance impact depends on system use and data processed.

Mitigation Strategies

Upgrade GPAC to version abi-16.23 or apply the patch 49dee5cad329cfed310c1682703df7daa47df31a. Avoid processing untrusted MP4 files with the -nstatx option until patched.
