|CVSS SCORE||8.4, (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)|
This vulnerability allows local attackers to escalate privileges on vulnerable installations of Microsoft Windows. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the kernel-mode routines that output text to a device context. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to escalate privilege to the level of SYSTEM.
Microsoft has issued an update to correct this vulnerability. More details can be found at:
