TITLE:
xine-lib Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA31502

VERIFY ADVISORY:
http://secunia.com/advisories/31502/

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) Multiple integer overflows exist within the processing of ID3 tags
in src/demuxers/id3.c. These can be exploited to cause heap-based
buffer overflows via overly large ID3 frame header size fields.

2) Multiple boundary errors exist within the
"demux_real_send_chunk()" function in src/demuxers/demux_real.c.
These can potentially be exploited to cause heap-based buffer
overflows via specially crafted Real Media files.

3) A boundary error exists within the "open_video_capture_device()"
function in src/input/input_v4l.c. This can be exploited to cause a
heap-based buffer overflow via a specially crafted V4L stream.

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

The vulnerabilities are reported in versions prior to 1.1.15.

SOLUTION:
Update to version 1.1.15.

PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
