<synopsis>
|

MPlayer makes use of the FFmpeg library, which is vulnerable to a heap
|
||
|
|
overflow in the avcodec_default_get_buffer() function discovered by
|
||
|
|
Simon Kilvington (see GLSA 200601-06). Furthermore, AFI Security
|
||
|
|
Research discovered two integer overflows in ASF file format decoding,
|
||
|
|
in the new_demux_packet() function from libmpdemux/demuxer.h and the
|
||
|
|
demux_asf_read_packet() function from libmpdemux/demux_asf.c.

<p>
|
||
|
|
An attacker could craft a malicious media file which, when opened using
|
||
|
|
MPlayer, would lead to a heap-based buffer overflow. This could result
|
||
|
|
in the execution of arbitrary code with the permissions of the user
|
||
|
|
running MPlayer.

|
||
|
|
<workaround>
|
||
|
|
<p>
|
||
|
|
There is no known workaround at this time.

All MPlayer users should upgrade to the latest version:
