The vulnerability could allow security feature bypass if an attacker uses the vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability, that takes advantage of the ASLR bypass to run arbitrary code. This security update is rated Important for all supported editions of Windows 7, Windows Server 2008 R2, Windows 8, Windows 8.1, Windows Server 2012, Windows Server 2012 R2, Windows RT, and Windows RT 8.1. Affected Software Windows 7 Windows Server 2008 R2 Windows 8 Windows 8.1 Windows Server 2012 Windows Server 2012 R2 Windows RT and Windows RT 8.1. Vulnerability Information A security feature bypass vulnerability exists in Microsoft Remote Procedure Call (LRPC). The problem is that an LRPC server may leak the message it receives from the client if the message is of a specific type and has a data view attached (which is not expected for messages of the type). RPC considers this an error and returns, but does not free the message. This allows the client to fill up the address space of the server with such messages. To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2014-0316. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
