CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
MPlayer 1.x

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

1) A boundary error exists within the libmpdemux/demux_audio.c file
when parsing FLAC comments. This can be exploited to corrupt memory
via a specially crafted FLAC file.

2) An array indexing error exists within the libmpdemux/demux_mov.c
file when parsing MOV file headers. This can be exploited to corrupt
heap memory via a specially crafted MOV file.

3) A boundary error exists within the "url_scape_string()" function
in stream/url.c. This can be exploited to cause a buffer overflow via
a specially crafted URL.

Successful exploitation allows execution of arbitrary code.

The vulnerabilities are reported in version 1.0rc2. Prior versions
may also be affected.

SOLUTION:
Apply vendor patches.
