TITLE:

SECUNIA ADVISORY ID:
SA31567

VERIFY ADVISORY:
http://secunia.com/advisories/31567/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
xine-lib 1.x
http://secunia.com/product/3410/

DESCRIPTION:
Some vulnerabilities have been reported in xine-lib, which
potentially can be exploited by malicious people to compromise a
user's system.

1) An integer overflow error exists within the "open_ra_file()"
function in src/demuxers/demux_realaudio.c. This can be exploited to
cause a heap-based buffer overflow via a specially crafted RealAudio
file.

2) A boundary error exists within the "parse_block_group()" function
in src/demuxers/demux_matroska.c. This can be exploited to cause a
heap-based buffer overflow via a specially crafted "Matroska" file.

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code.

The vulnerabilities are reported in version 1.1.14 and 1.1.15. Other
versions may also be affected.

SOLUTION:
Do not open untrusted files or streams with applications using
xine-lib.
