Описание
A flaw was found in FFmpeg. An uncontrolled resource consumption vulnerability exists in the IAMF demuxer. An unauthenticated attacker can exploit this by supplying a specially crafted input file with a malicious count_label field. This can cause the system to allocate a large amount of memory, leading to resource exhaustion and a denial of service.

FFmpeg through 8.1.2, fixed in commit 5d7112c, contains an uncontrolled resource consumption vulnerability in the IAMF demuxer that allows an unauthenticated attacker to cause multi-gigabyte memory allocation from a 17-byte input file by supplying a crafted count_label field. The mix_presentation_obu() function in libavformat/iamf_parse.c calls av_calloc(count_label, sizeof(*language_label)) with an attacker-controlled value before validating available OBU data, enabling an allocation amplification of approximately 126 million bytes per input byte that exhausts process memory or triggers an OOM-kill during format probing.
