Description

 A local overflow exists in Kaspersky Anti-Virus. The_NtSetValueKey() function in the klif.sys file fails to properly parse the data size argument resulting in a kernel heap overflow. With a specially crafted request, an attacker can cause corruption of kernel memory and may let an attacker overwrite a nearly arbitrary amount of kernel heap memory with arbitrary data resulting in a loss of integrity.
