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.
xine-lib before 1.1.15 allows remote attackers to cause a denial of service (crash) via a crafted OGG file, as demonstrated by playing lol-ffplay.ogg with xine.
Stack-based buffer overflow in the demux_nsf_send_chunk function in src/demuxers/demux_nsf.c in xine-lib 1.1.12 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long NSF title.
