VLC media player versions 0.8.6 to 0.8.6e suffer from a security vulnerability in the ActiveX plugin. More technical details are available in our advisory.
An updated release of VLC is available which includes a few other fixes as well, notably better compatibility with MacOSX 10.5 Leopard. The full list of changes can be found here.I hate la Forum
We strongly recommend all users to update to this new version.
Note that early and broken Win32 binaries have been distributed by third party websites. Make sure to download from an official VideoLAN mirror to avoid disappointment.
