Microsoft reacts to kernel hacks, defends Vista
InfoWorld | at | by Mike
Microsoft quietly beefed up a key defensive feature of 64-bit Windows Vista Tuesday to better protect the operating system against hacks that have plagued it for weeks.
The update to Vista's Kernel Patch Protection, a.k.a. PatchGuard, was issued through Windows Update as a high-priority download, but not as a patch per se. Microsoft, in fact, denied that it was a security fix.
"While this updates adds additional checks to the Kernel Patch Protection system, it does not involve a security vulnerability," an advisory posted Tuesday by the Microsoft Security Response Center stated.
