Four vulnerabilities were reported found in Windows, three of which could lead to escalation of privilege and one could lead to denial of service condition.
Microsoft has released a security update to address four reported vulnerabilities in the Windows kernel-mode driver. Three of the vulnerabilities were caused by improper handling of objects in memory; they could be exploited into allowing an attacker to gain escalated privileges and read arbitrary amounts of kernel memory. The other one vulnerability was caused by improper handling of a specially crafted font file, and upon successful exploitation, it could cause the system to stop responding and restart.
All of the issues have been fixed in the latest update by correcting the way that objects in memory and specially crafted font files are handled. Users are recommended to install the update as a protection measure against possible exploit attempts.
