Discussion

Windows Kernel Font Buffer Overflow Vulnerability

The Microsoft Windows Kernel is prone to a locally exploitable privilege-escalation vulnerability that is casued by an unchecked buffer when handling malicious fonts. Local attackers may be able to completely compromise vulnerable computers.

Exploitation attempts could also result in a denial of service. Microsoft has reported that the vulnerability will most likely cause a denial of service on Windows XP SP2 platforms. The vendor has also stated that this vulnerability is not critical on Windows 98/98SE/ME, possibly because of lack of multiuser support on the operating system.
