VLC attempt dereference an invalid memory address, and a crash will ensure.

Impact

In the failure case, VLC will dereference a memory address within the first

protection fault on Windows), and the process will terminate abruptly.

In most usage scenarii, this will only cause user annoyance.

Threat mitigation

Exploitation of this issue requires the user to include a file in its playlist 
or to attempt to open it.

Workarounds

The user should refrain from opening files from untrusted third parties or 
accessing untrusted remote sites (or disable the VLC browser plugins), until 
the patch is applied.

Solution

VLC media player 1.1.3 [will address] this issue. Patches for VLC media player 
1.1.x and 1.0.x are available from the corresponding official VLC source code 
repositories.
