Description Preview

A heap-based buffer overflow vulnerability (CWE-787) exists in the GetGhostNum function of the stbl_read.c file in gpac version 0.8.0. When processing crafted input files, the vulnerability can be triggered, leading to a denial of service condition. This issue occurs due to improper bounds checking when handling buffer operations, allowing an attacker to potentially crash the application by providing specially crafted input data.

Overview

GPAC is an open-source multimedia framework used for research and academic purposes as well as for deployment in media players and servers. The vulnerability affects version 0.8.0 of the software. The heap-based buffer overflow in the GetGhostNum function can be exploited by an attacker who provides a specially crafted input file to the application. When processed, this malicious input can cause the application to write data beyond the allocated heap buffer boundaries, resulting in memory corruption and potential application crashes. This vulnerability is particularly concerning in scenarios where GPAC is used to process untrusted media files from external sources.

Remediation

Users of gpac 0.8.0 should upgrade to the latest version that contains the fix for this vulnerability. System administrators and developers should ensure that any applications using the GPAC framework are updated accordingly. If immediate patching is not possible, consider implementing the following mitigations:

  1. Avoid processing untrusted media files with affected versions of GPAC
  2. Implement additional validation for input files before processing them with GPAC
  3. Run GPAC in a sandboxed environment to minimize the impact of potential exploitation
  4. Monitor system logs for unexpected crashes of applications using GPAC that might indicate exploitation attempts
