Description


A vulnerability has been reported in AnyDVD, which can be exploited by malicious, local users to cause a DoS (Denial of Service) or to potentially gain escalated privileges.

The vulnerability is caused due to insufficient validation of user space data provided to the ElbyCDIO.sys kernel driver. This can be exploited to trigger a memory corruption and potentially execute arbitrary code in kernel space via a specially crafted IOCTL request.

The vulnerability is reported in versions 6.5.2.2 and prior.


Solution:
Update to version 6.5.2.6 or later.
