DESCRIPTION:
Some vulnerabilities have been reported in MPlayer, which potentially
can be exploited by malicious people to compromise a user's system.
The vulnerabilities are caused due to multiple integer underflow
errors within the "demux_real_fill_buffer()" function in
libmpdemux/demux_real.c. These can be exploited to cause heap-based
buffer overflows via specially crafted Real Media files.
Successful exploitation may allow execution of arbitrary code.
The vulnerabilities are reported in version 1.0rc2. Other versions
may also be affected.
SOLUTION:
Do not open untrusted files or streams using MPlayer.
