xine-lib parse_block_group() function buffer overflow
| xinelib-parseblockgroup-bo (44634) |  High Risk |
Description:
xine-lib is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the parse_block_group() function. By persuading a victim to open a Matroska file containing a specially-crafted EBML element length, a remote attacker could exploit this vulnerability to overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.

- CVE-2008-5236: 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.
