Microsoft released MS08-067 security patch on Thursday, rated as critical.
This security update resolves a vulnerability in the Server
service that affects all currently supported versions of
Windows. Windows XP and older versions are rated as
critical while Windows Vista and newer versions are rated
as important. Because the vulnerability is potentially
wormable on those older versions of Windows Microsoft is
encouraging customers to test and deploy the update as soon
as possible.
In addition, to releasing a security update to address the
vulnerability, Micrisoft said that it had taken steps to
help enable broader protections for customers.
Microsoft said that they had discovered this vulnerability
as part of their research into a limited series of targeted
malware attacks against Windows XP systems that they
discovered about two weeks ago through their ongoing
monitoring.
"As we investigated these attacks we found they were
utilizing a new vulnerability and initiated our Software
Security Incident Response Process (SSIRP). As we analyzed
the vulnerability in our SSRP process, we found that this
vulnerability was potentially wormable on Windows XP and
older systems," Microsoft said. "Our analysis also showed
that it would be possible to address this vulnerability in
a way that would enable us to develop an update of
appropriate quality for broad distribution quickly," the
company added.
