In libavcodec in Libav 9.21, ff_h264_execute_ref_pic_marking() has a heap-based buffer over-read.
In Libav 12.3, there is a floating point exception in the range_decode_culshift function (called from range_decode_bits) in libavcodec/apedec.c that will lead to remote denial of service via crafted input.
In Libav 12.3, a NULL pointer dereference (RIP points to zero) issue in ff_mpa_synth_filter_float in libavcodec/mpegaudiodsp_template.c can cause a segmentation fault (application crash) via a crafted mov file.
In Libav 12.3, there is a heap-based buffer over-read in decode_frame in libavcodec/lcldec.c that allows an attacker to cause denial-of-service via a crafted avi file.
There exists a NULL pointer dereference in ff_vc1_parse_frame_header_adv in vc1.c in Libav 12.3, which allows attackers to cause a denial-of-service through a crafted aac file.
FFmpeg before commit 9807d3976be0e92e4ece3b4b1701be894cd7c2e1 contains a CWE-835: Infinite loop vulnerability in pva format demuxer that can result in a Vulnerability that allows attackers to consume excessive amount of resources like CPU and RAM. This attack appear to be exploitable via specially crafted PVA file has to be provided as input. This vulnerability appears to have been fixed in 9807d3976be0e92e4ece3b4b1701be894cd7c2e1 and later.
FFmpeg before commit cced03dd667a5df6df8fd40d8de0bff477ee02e8 contains multiple out of array access vulnerabilities in the mms protocol that can result in attackers accessing out of bound data.
