TITLE:
MPlayer Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA13508

VERIFY ADVISORY:
http://secunia.com/advisories/13508/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
From remote

SOFTWARE:
MPlayer 1.x
http://secunia.com/product/2255/

DESCRIPTION:
Multiple vulnerabilities have been reported in MPlayer, which can be
exploited by malicious people to compromise a user's system.

1) An integer overflow in the "real_setup_and_get_header()" function
when processing RTSP streams can be exploited to cause a heap-based
buffer overflow by passing an extremely large "Content-Length" for a
stream.

2) A boundary error in the "get_media_packet()" function when
handling MMST streams can be exploited to cause a stack-based buffer
overflow via a specially crafted file containing an overly large
value in the "length" field.

3) A boundary error in the "demux_open_bmp()" function when parsing
bitmaps can be exploited to cause a heap-based buffer overflow via a
specially crafted bitmap image containing an overly large value in
the "biClrUsed" field.

4) An unspecified boundary error within the PNM streaming code can be
exploited to cause a heap-based buffer overflow.

5) An unspecified boundary error within mp3lib can be exploited to
cause a buffer overflow.

The vulnerabilities have been reported in version 1.0pre5 and the CVS
version. Prior versions may also be affected.

SOLUTION:
The vulnerabilities have been fixed in version 1.0pre5try2.
