CVE-2023-46426: 
Linux Debian vulnerability analysis and mitigation

Overview

A Heap-based Buffer Overflow vulnerability was discovered in gpac version 2.3-DEV-rev588-g7edc40fee-master. The vulnerability exists in the gffwrite component located in utils/osfile.c. This security flaw allows remote attackers to execute arbitrary code and cause a denial of service (DoS) via the gf_fwrite component (NVD).

Technical details

The vulnerability is identified as a heap-based buffer overflow occurring at utils/osfile.c:1657 in the gffwrite function. The issue manifests when processing certain SWF files, specifically during the parsing of PlaceObject tags. The vulnerability has been assigned a CVSS v3.1 base score of 8.8 (HIGH) with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H (NVD).

Impact

The vulnerability can lead to arbitrary code execution and denial of service conditions. When exploited, it allows attackers to perform a READ operation of size 53248 bytes outside the allocated buffer boundaries, potentially leading to system compromise or service disruption (Github Issue).

Mitigation and workarounds

The vulnerability has been addressed in subsequent versions of gpac. Users are advised to update to a version after commit 14ec709, which includes the fix for this buffer overflow issue (Github Issue).
