CVSS 7.5 · High EPSS 0,73%

Kerentanan Loop with Unreachable Exit Condition ('Infinite Loop') pada ffmpeg. Skor CVSS 3.1 7.5 (High) menurut vulncheck.com.

Deskripsi (NVD)

FFmpeg versions 0.6.3 through 8.1.2 contain an infinite loop vulnerability in the RTP/ASF demuxer within libavformat/rtpdec_asf.c that allows remote attackers to cause denial of service by sending a crafted RTP/ASF stream. The rtp_asf_fix_header function fails to validate a minimum chunksize when iterating over ASF objects, causing the loop pointer to never advance when a chunksize is smaller than the 24-byte minimum ASF object header size, resulting in CPU exhaustion that denies service to legitimate users.
