A specially-crafted Java application, utilizing the functionality of org.videolan.BDJLoader class, could use this missing feature to perform actions as the user running the Bluray player application. Note: libbluray upstream disables BD-J support by default, but some downstreams (like Fedora) pass --enable-bdjava at configure time, enabling it for their distribution. (This may affect proprietary BD-J implementations as well, I haven't investigated this due to lack of hardware and documentation.)Could we finally get a CVE ID for this? Thanks.Btw, aren't those security issues fixed now?
I don't know. There is a BDJSecurityManager, but I'm not convinced it's sufficiently strict. For instance, the checkPermission(Permission) method does not call checkWrite(String) for FilePermission objects at all. This does not look right, but I'm not familiar with the finer points of Java sandboxing. Anyway, I can't test this due to lack of a BD-J production environment, sorry. Florian
