MPlayer MMST and RTSP Buffer Overflows Let Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1013771
SecurityTracker URL:  http://securitytracker.com/id/1013771
CVE Reference:   CVE-2005-1195   (Links to External Site)
Updated:  Jul 12 2005
Original Entry Date:  Apr 20 2005
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 1.0pre6 and prior versions
Description:   Two vulnerabilities were reported in MPlayer in the processing of MMST streams and RealMedia RTSP streams. A remote user can execute arbitrary code on a connected player.

A remote server can supply specially crafted streaming MMS/TCP data to trigger a buffer overflow in the player. The player does not limit the number of MMST stream IDs, allowing a malicious server to announce more than 20 streams to overflow the array.

A remote server can also supply specially crafted RealMedia RTSP data to trigger a separate buffer overflow. The player does not limit the number of lines stored in an array with MAX_FIELDS elements, allowing a malicious server to send more than MAX_FIELDS lines to overflow the array.

Impact:   A remote server can execute arbitrary code on a target user's connected player. The code will run with the privileges of the target user.
Solution:   The vendor has issued a fixed version (1.0pre7 and later versions).

CVS HEAD versions posted after Fri Apr 15 23:31:57 2005 UTC also include the fix.
