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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
