Integer overflow in the qt_error parse_trak_atom function in demuxers/demux_qt.c in xine-lib 1.1.16.2 and earlier allows remote attackers to execute arbitrary code via a Quicktime movie file with a large count value in an STTS atom, which triggers a heap-based buffer overflow.
xine-lib 1.1.12, and other 1.1.15 and earlier versions, relies on an untrusted input value to determine the memory allocation and does not check the result for (1) the MATROSKA_ID_TR_CODECPRIVATE track entry element processed by demux_matroska.c; and (2) PROP_TAG, (3) MDPR_TAG, and (4) CONT_TAG chunks processed by the real_parse_headers function in demux_real.c; which allows remote attackers to cause a denial of service (NULL pointer dereference and crash) or possibly execute arbitrary code via a crafted value.
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).
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.
The real_parse_headers function in demux_real.c in xine-lib 1.1.12, and other 1.1.15 and earlier versions, relies on an untrusted input length value to "reindex into an allocated buffer," which allows remote attackers to cause a denial of service (crash) via a crafted value, probably an array index error.
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.
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.
