TITLE:

SECUNIA ADVISORY ID:
SA29484

VERIFY ADVISORY:
http://secunia.com/advisories/29484/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

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

DESCRIPTION:
Luigi Auriemma has reported some vulnerabilities in xine-lib, which
potentially can be exploited by malicious people to compromise a
user's system.

The vulnerabilities are caused due to integer overflow errors when
allocating memory in src/demuxers/demux_flv.c,
src/demuxers/demux_qt.c, src/demuxers/demux_real.c,
src/demuxers/demux_wc3movie.c, src/demuxers/ebml.c, and
src/demuxers/demux_film.c. These can be exploited to cause heap-based
buffer overflows via overly large fields included in e.g. FLV, MOV,
RM, MVE, MKV, and CAK files.

The vulnerabilities are reported in version 1.1.11. Other versions
may also be affected.

SOLUTION:
Do not open untrusted files using xine-lib.
