Microsoft Windows splwow64 Untrusted Pointer Dereference Privilege Escalation Exploit Update

The specific flaw exists within the user-mode printer driver host process splwow64.exe. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to escalate privileges from low integrity and execute code in the context of the current user at medium integrity.



This update improves the reliability and adds support for more patch levels.
