| Detailed Description |
The Hotfix (MS15-135, 3119075) for 'Security Update for Windows Kernel-Mode Drivers to Address Elevation of Privilege' has not been applied.
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker logs on to a target system and runs a specially crafted application that, by way of a race condition, results in references to memory locations that have already been freed. Microsoft Message Queuing (MSMQ) must be installed and the Windows Pragmatic General Multicast (PGM) protocol specifically enabled for a system to be vulnerable. MSMQ is not present in default configurations and, if it is installed, the PGM protocol is available but disabled by default.
Windows PGM UAF Elevation of Privilege Vulnerability - CVE-2015-6126
An elevation of privilege vulnerability exists in the Windows Pragmatic General Multicast (PGM) protocol that is caused when an attacker-induced race condition results in references to memory contents that have already been freed. An attacker who successfully exploited this vulnerability could execute code with elevated privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
* Note: This check requires an account with administrative privileges which can log into the host to scan. Absence of this condition will result in the check not being performed and a False Negative for all vulnerable hosts.
