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.
Solution:
Update to version 7.0.1.321 (MP1).
