Microsoft Windows Multiple Kernel Vulnerabilities

-

Description


Three vulnerabilities have been reported in Microsoft Windows, which can be exploited by malicious, local users to gain escalated privileges and by malicious people to potentially compromise a user's system.

1) An input validation error when passing input from user-mode through the kernel component of GDI may potentially be exploited to run arbitrary code in kernel mode by e.g. tricking a user into viewing a specially crafted EMF or WMF image file hosted on a malicious website.

2) An error in the kernel when validating handles may be exploited by unprivileged users to run arbitrary code with escalated privileges.

3) An error in the kernel when handling certain invalid pointers may be exploited by unprivileged users to run arbitrary code with escalated privileges.


Solution:
Apply patches.
