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

1) A boundary error when processing lines from RealMedia RTSP streams
can be exploited to cause a heap-based buffer overflow via a specially
crafted response with a large amount of lines.

Successful exploitation may allow execution of arbitrary code.

2) A boundary error when processing stream IDs from Microsoft Media
Services MMST streams can be exploited to cause a heap-based buffer
overflow via a specially crafted response with more than 20 stream
IDs.

Successful exploitation may allow execution of arbitrary code.

The vulnerabilities have been reported in versions 1.0pre6 and prior.

SOLUTION:
Update to version 1.0pre7.
