Details

A remote user could create a specifically crafted file that could trigger a buffer overflow in VLC's H26X packetizer

Impact

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

Threat mitigation

Exploitation of those issues requires the user to explicitly open a specially crafted file or stream.

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.
