TITLE:
KV AntiVirus 2010 Local Denial of Service Vulnerabilities

SECUNIA ADVISORY ID:
SA39667

VERIFY ADVISORY:
http://secunia.com/advisories/39667/

DESCRIPTION:
Some vulnerabilities have been reported in KV AntiVirus 2010, which
can be exploited by malicious, local users to cause a DoS (Denial of
Service).

1) Multiple errors in KRegEx.sys when processing parameters passed to
various hooked functions (e.g. "NtCreateKey()", "NtOpenKey()") can be
exploited to crash an affected system.

2) A NULL-pointer dereference error in the KRegEx.sys driver can be
exploited to cause a system crash via a specially crafted 0x88008068
IOCTL.

The vulnerabilities are reported in versions prior to 13.0.10.111.

SOLUTION:
Update to version 13.0.10.111.
