SYNTHESIS OF THE VULNERABILITY

An attacker can use a freed memory area in the Print Spooler of
Windows, in order to trigger a denial of service, and possibly to
execute privileged code.

Impacted products: Windows 2008, Microsoft Windows 2012, Windows
7, Windows 8, Windows RT, Windows Vista

Severity: 2/4

Creation date: 11/06/2013

DESCRIPTION OF THE VULNERABILITY

The Print Spooler of Windows processes print tasks.

However, when the connection to a printer is removed, a memory
area is not correctly freed. Technical details are unknown.

An attacker can therefore use a freed memory area in the Print
Spooler of Windows, in order to trigger a denial of service, and
possibly to execute privileged code.
