Versions 5.0 - 7.0 of ESET Smart Security and ESET Endpoint Security
products for Windows XP OS allow a low privileged user to execute code
as SYSTEM by exploiting a vulnerability in the ESET Personal Firewall
NDIS filter (EpFwNdis.sys) kernel mode driver also mentioned as Personal
Firewall module Build 1183 (20140214) and prior. This is a 'trusted
value vulnerability' that can be triggered through a specific IOCTL with
a specifically crafted buffer, to force the driver to validate an
improper IOCTL.
