SlySoft AnyDVD is capable of removing unwanted movie features, including subtitles and prohibition messages such as copyright and FBI warnings. It also allows you to launch an external application whenever you insert or remove a disc, or prevent 'PC-friendly' software from automatically launching when you insert a video DVD.
Positive Technologies Research Team has discovered multiple memory corruption vulnerabilities in SlySoft products.
The IOCTL handler in ElbyCDIO.sys 18.104.22.168 and earlier, shipped with AnyDVD, Virtual CloneDrive, CloneDVD and CloneCD, uses the METHOD_NEITHER communication method for IOCTLs and does not properly validate buffer data associated with the Irp object, which allows local users to crash the system.
Update AnyDVD to version 22.214.171.124.
Update CloneDVD to version 126.96.36.199.
Update Virtual CloneDrive to version 188.8.131.52.
