DESCRIPTION:
A vulnerability has been reported in AVG Internet Security, which can
be exploited by malicious, local users to cause a DoS (Denial of
Service).

The vulnerability is caused due to an error in the avgtdix.sys driver
when processing IOCTLs. This can be exploited to corrupt kernel memory
and cause a crash via a specially crafted 0x830020C8 IOCTL.

The vulnerability is reported in AVG Internet Security version
9.0.851 and 9.0.864 and avgtdix.sys version 9.0.0.832. Other versions
may also be affected.
