A stack-based buffer overflow in the subtitle decoder in Libav 12.3 allows attackers to corrupt the stack via a crafted video file in Matroska format, because srt_to_ass in libavcodec/srtdec.c misuses snprintf.

A stack-based buffer overflow in the subtitle decoder in Libav 12.3 allows attackers to corrupt the stack via a crafted video file in Matroska format, because srt_to_ass in libavcodec/srtdec.c misuses snprintf. NOTE: Third parties dispute that this is a vulnerability because “no evidence of a vulnerability is provided” and only “a generic warning from a static code analysis” is provided

In Libav 12.3, a denial of service in the subtitle decoder allows attackers to hog the CPU via a crafted video file in Matroska format, because srt_to_ass in libavcodec/srtdec.c has a complex format argument to sscanf.

The av_audio_fifo_size function in libavutil/audio_fifo.c in Libav 12.2 allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted media file.

The pcm_encode_frame function in libavcodec/pcm.c in Libav 12.2 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted media file.

The mpc8_probe function in libavformat/mpc8.c in Libav 12.2 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted audio file.

The stereo_processing function in libavcodec/aacps.c in Libav 12.2 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted aac file, related to ff_ps_apply.

The unpack_parse_unit function in libavcodec/dirac_parser.c in Libav 12.2 allows remote attackers to cause a denial of service (segmentation fault) via a crafted file.

The apply_dependent_coupling function in libavcodec/aacdec.c in Libav 12.2 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted aac file.

In Libav through 12.2, there is an invalid memcpy in the av_packet_ref function of libavcodec/avpacket.c. Remote attackers could leverage this vulnerability to cause a denial of service (segmentation fault) via a crafted avi file.

In Libav through 12.2, there is an invalid memcpy call in the ff_mov_read_stsd_entries function of libavformat/mov.c. Remote attackers could leverage this vulnerability to cause a denial of service (segmentation fault) and program failure with a crafted avi file.

The ff_free_picture_tables function in libavcodec/mpegpicture.c in Libav 12.2 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file, related to vc1_decode_i_blocks_adv.

The ff_vc1_mc_4mv_chroma4 function in libavcodec/vc1_mc.c in Libav 12.2 allows remote attackers to cause a denial of service (segmentation fault and application crash) or possibly have unspecified other impact via a crafted file.

The h264_slice_init function in libavcodec/h264_slice.c in Libav 12.2 allows remote attackers to cause a denial of service (segmentation fault and application crash) via a crafted file.

The vc1_decode_frame function in libavcodec/vc1dec.c in Libav 12.2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted file.
