Synopsis

========

 

Multiple vulnerabilities in MPlayer may lead to the execution of

arbitrary code or a Denial of Service.

 

Background

==========

 

MPlayer is a media player including support for a wide range of audio

and video formats.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 mplayer < 1.0_rc2_p28058-r1 >= 1.0_rc2_p28058-r1

 

Description

===========

 

Multiple vulnerabilities have been reported in MPlayer:

 

* A stack-based buffer overflow was found in the str_read_packet()

function in libavformat/psxstr.c when processing crafted STR files

that interleave audio and video sectors (CVE-2008-3162).

 

* Felipe Andres Manzano reported multiple integer underflows in the

demux_real_fill_buffer() function in demux_real.c when processing

crafted Real Media files that cause the stream_read() function to

read or write arbitrary memory (CVE-2008-3827).

 

* Tobias Klein reported a stack-based buffer overflow in the

demux_open_vqf() function in libmpdemux/demux_vqf.c when processing

malformed TwinVQ files (CVE-2008-5616).

 

Impact

======

 

A remote attacker could entice a user to open a specially crafted STR,

Real Media, or TwinVQ file to execute arbitrary code or cause a Denial

of Service.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All MPlayer users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose

">=media-video/mplayer-1.0_rc2_p28058-r1 "
