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.
