Windows IP Options Remote Compromise

Summary:

X-force has discovered a vulnerability in Windows NT-based IP Stack drivers.
This vulnerability affects most modern Windows operating systems, and could
allow for remote compromise of networked systems. This vulnerability is
trivially exploitable to cause a denial of service condition, and may be
exploited to gain access to affected systems. In most cases, but not in
all, exploitation of this issue will be limited to the local subnet.

Business Impact:

Successful exploitation of this vulnerability could be leveraged to
gain complete control over target systems, and might lead to malware
installation, exposure of confidential information, or further network
compromise. Due to the widespread use of the affected operating systems
and the critical nature of component affected, it is likely that
servers and desktops used for a wide variety of purposes are
vulnerable to this issue.
