"The remote Windows host has a version of AVG Internet Security
installed that is 2013.x prior to 2013.3495 or 2015.x prior to
2015.5557. It is, therefore, affected by a local privilege escalation
vulnerability due to a flaw in the TDI driver (avgtdix.sys) that
occurs when handling 0x830020f8 IOCTL calls. A local attacker can
exploit this, via a crafted 0x830020f8 IOCTL call, to write controlled
data to an arbitrary memory location, resulting in arbitrary code
execution with kernel-level privileges.");
