CVE-2026-64834

CVE-2026-64834

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.

CVE-2026-64834

A flaw was found in FFmpeg. A remote attacker can exploit an infinite loop vulnerability in the RTP/ASF demuxer by sending a specially crafted stream. This vulnerability occurs because the rtp_asf_fix_header function does not properly validate the size of data chunks, preventing the processing loop from advancing. Successful exploitation leads to CPU exhaustion, causing a Denial of Service (DoS) for legitimate users.
