“ Details
A remote user could create a specifically crafted file that could trigger some various issues.
It is possible to trigger a remote code execution through a specifically crafted playlist, and tricking the user into interracting with that playlist elements.
This is explained in more details on the reporter's article
It is also possible to trigger read or write buffer overflows with some crafted files or by a MITM attack on the automatic updater
If successful, a malicious third party could trigger either a crash of VLC or an arbitratry code execution with the privileges of the target user.
While these issues in themselves are most likely to just crash the player, we can't exclude that they could be combined to leak user informations or remotely execute code. ASLR and DEP help reduce the likelyness of code execution, but may be bypassed.
We have not seen exploits performing code execution through these vulnerability
