MPlayer MMST and Real RTSP Multiple Heap Overflows
------------------------------------------------------------------------
SUMMARY
Buffer Overflows were found in MpPayer MMST and Real RTSP allow attackers
to execute arbitrary code.
DETAILS
Vulnerable Systems:
* MPlayer version 1.0pre6 and prior (including pre6a)
Immune Systems:
* MPlayer version 1.0pre7
Two vulnerabilities were identified in MPlayer, which could be exploited
by remote attackers to execute arbitrary commands. The first flaw is due
to a heap overflow error in the MMST code when handling multiple stream
IDs, which may be exploited via a malicious server to compromise a
vulnerable system. The second vulnerability is due to a heap overflow
error in the Real RTSP code when processing multiple lines (more than
"MAX_FIELDS" lines), which may be exploited via a malicious server to
cause a denial of service and potentially compromise a vulnerable system.
Vendor Status:
The vendor has released patch:
