Ffmpeg vulnerability analysis and mitigation
Overview
CVE-2025-0518 is an Unchecked Return Value and Out-of-bounds Read vulnerability discovered in FFmpeg version 7.1. The vulnerability affects the program files in libavfilter/af_pan.c and allows attackers to read sensitive constants within an executable. The issue was discovered by Simcha Kosman and has been fixed through a GitHub commit (FFmpeg Commit).
Technical details
The vulnerability stems from improper handling of return values from sscanf() function in the af_pan.c file. The issue occurs in the initialization function where sscanf() is used to parse gain values. The fix involves adding a proper check for the sscanf() return value to ensure it is greater than or equal to 1 before proceeding with further operations (FFmpeg Commit).
Impact
The vulnerability allows attackers to read sensitive constants within an executable, which could potentially expose sensitive information or lead to further exploitation of the system (CVE Mitre).
Mitigation and workarounds
The vulnerability has been fixed through a commit (b5b6391d64807578ab872dc58fb8aa621dcfc38a) that properly checks the return value of sscanf(). Users are advised to update to the patched version of FFmpeg that includes this fix (FFmpeg Commit).
