demux_qt.c in xine-lib 1.1.12, and other 1.1.15 and earlier versions, does not validate the count field before calling calloc for STSD_ATOM atom allocation, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted media file.

xine-lib 1.1.12, and other 1.1.15 and earlier versions, does not properly handle (a) negative and (b) zero values during unspecified read function calls in input_file.c, input_net.c, input_smb.c, and input_http.c, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via vectors such as (1) a file or (2) an HTTP response, which triggers consequences such as out-of-bounds reads and heap-based buffer overflows.

Multiple heap-based buffer overflows in xine-lib 1.1.12, and other 1.1.15 and earlier versions, allow remote attackers to execute arbitrary code via vectors related to (1) a crafted EBML element length processed by the parse_block_group function in demux_matroska.c; (2) a certain combination of sps, w, and h values processed by the real_parse_audio_specific_data and demux_real_send_chunk functions in demux_real.c; and (3) an unspecified combination of three values processed by the open_ra_file function in demux_realaudio.c. NOTE: vector 2 reportedly exists because of an incomplete fix in 1.1.15.

Unspecified vulnerability in xine-lib before 1.1.15 has unknown impact and attack vectors related to libfaad. NOTE: due to the lack of details, it is not clear whether this is an issue in xine-lib or in libfaad.

xine-lib before 1.1.15 performs V4L video frame preallocation before ascertaining the required length, which has unknown impact and attack vectors, possibly related to a buffer overflow in the open_video_capture_device function in src/input/input_v4l.c.

xine-lib 1.1.12, and other versions before 1.1.15, does not check for failure of malloc in circumstances including (1) the mymng_process_header function in demux_mng.c, (2) the open_mod_file function in demux_mod.c, and (3) frame_buffer allocation in the real_parse_audio_specific_data function in demux_real.c, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted media file.

xine-lib before 1.1.15 allows remote attackers to cause a denial of service (crash) via "MP3 files with metadata consisting only of separators."

Integer underflow in demux_qt.c in xine-lib 1.1.12, and other 1.1.15 and earlier versions, allows remote attackers to cause a denial of service (crash) via a crafted media file that results in a small value of moov_atom_size in a compressed MOV (aka CMOV_ATOM).

Heap-based buffer overflow in the demux_real_send_chunk function in src/demuxers/demux_real.c in xine-lib before 1.1.15 allows remote attackers to execute arbitrary code via a crafted Real Media file. NOTE: some of these details are obtained from third party information.

The real_parse_audio_specific_data function in demux_real.c in xine-lib 1.1.12, and other 1.1.15 and earlier versions, uses an untrusted height (aka codec_data_length) value as a divisor, which allow remote attackers to cause a denial of service (divide-by-zero error and crash) via a zero value.
