Memory leak in the Local RPC (LRPC) server implementation in Microsoft Windows 7 SP1, Windows Server 2008 R2 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1 allows remote attackers to cause a denial of service (memory consumption) and bypass the ASLR protection mechanism via a crafted client that sends messages with an invalid data view, aka "LRPC ASLR Bypass Vulnerability."
