DESCRIPTION:
mu-b has reported some vulnerabilities in DESlock+, which can be
exploited by malicious, local users to cause a DoS (Denial of
Service) or gain escalated privileges.
The vulnerabilities are caused due to input validation errors in
DLMFDISK.sys and DLMFENC.sys and can be exploited to e.g. execute
arbitrary code with kernel privileges or cause the system to crash
via specially crafted arguments passed to certain IOCTL handlers.
The vulnerabilities are reported in version 3.2.6. Prior versions may
also be affected.
SOLUTION:
Update to version 3.2.7.
