Description
The issue is related to insufficient access restrictions in certain Windows functions. It allows a local attacker to gain elevated privileges by making a specially crafted Winsock call to an invalid address. To exploit this, an attacker must first log on to the target system. The vulnerability can be exploited via a crafted application that triggers a Winsock call referencing an invalid address.
Recommendations
For Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT Gold and 8.1, and Windows 10 Gold and 1511, update to a newer version that includes the fix for this issue.
As a temporary workaround, consider restricting access to the Winsock functionality until a patch is available.
Avoid using the
Winsock call with unverified memory addresses in applications until the issue is resolved.Fix
