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.

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.

In Libav through 11.11 and 12.x through 12.1, the smacker_decode_tree function in libavcodec/smacker.c does not properly restrict tree recursion, which allows remote attackers to cause a denial of service (bitstream.c:build_table() out-of-bounds read and application crash) via a crafted Smacker stream.

libav before 12.1 is vulnerable to an invalid read of size 1 due to NULL pointer dereferencing in the nsv_read_chunk function in libavformat/nsvdec.c.

The get_vlc2 function in get_bits.h in Libav 11.9 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted mp3 file. NOTE: this issue exists due to an incomplete fix for CVE-2016-8675.

The get_vlc2 function in get_bits.h in Libav before 11.9 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted mp3 file, possibly related to startcode sequences during m4v detection.

Stack-based buffer overflow in the aac_sync function in aac_parser.c in Libav before 11.5 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted file.

Heap-based buffer overflow in the ff_audio_resample function in resample.c in libav before 11.4 allows remote attackers to cause a denial of service (crash) via vectors related to buffer resizing.

The put_no_rnd_pixels8_xy2_mmx function in x86/rnd_template.c in libav 11.7 and earlier allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted MP3 file.

The mov_read_dref function in libavformat/mov.c in Libav before 11.7 and FFmpeg before 0.11 allows remote attackers to cause a denial of service (memory corruption) or execute arbitrary code via the entries value in a dref box in an MP4 file.

The ff_h263_decode_mba function in libavcodec/ituh263dec.c in Libav before 11.5 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a file with crafted dimensions.

The msrle_decode_pal4 function in msrledec.c in Libav before 10.7 and 11.x before 11.4 and FFmpeg before 2.0.7, 2.2.x before 2.2.15, 2.4.x before 2.4.8, 2.5.x before 2.5.6, and 2.6.x before 2.6.2 allows remote attackers to have unspecified impact via a crafted image, related to a pixel pointer, which triggers an out-of-bounds array access.
