DESCRIPTION:
EP_X0FF has reported some vulnerabilities in Kasperky AntiVirus,
which can be exploited by malicious, local users to cause a DoS
(Denial of Service).

The vulnerabilities are caused due to errors within klif.sys when
handling the parameters of certain hooked functions. These can be
exploited to cause a DoS by e.g. calling "NtCreateSection()",
"NtUserSendInput()", "LoadLibraryA()", or other unknown SSDT entries
with specially crafted parameters.

The vulnerabilities are reported in version 7.0 build 125. Other
versions may also be affected.

2007.
