Subject: [oCERT-2008-013] MPlayer Real demuxer heap overflow

2008/09/29 #2008-013 MPlayer Real demuxer heap overflow


The MPlayer multimedia player suffers from a vulnerability which could result
in arbitrary code execution and at the least, in unexpected process

Three integer underflows located in the Real demuxer code can be used to
exploit a heap overflow, a specific video file can be crafted in order to make
the stream_read function reading or writing arbitrary amounts of memory.

The following patch fixes the issue:

Affected version:

MPlayer <= 1.0_rc2

Fixed version:

MPlayer, N/A
