Secunia integrated with Microsoft WSUS

Description:
Ruben Santamarta has reported two vulnerabilities in Microsoft Windows, which can be exploited by malicious, local users to cause a DoS (Denial of Service) and gain escalated privileges.

1) An input validation error exists within the "MRxSmbCscIoctlOpenForCopyChunk()" function in MRXSMB.SYS when handling certain DeviceIoControl requests. This can be exploited to overwrite kernel memory and allows arbitrary code execution with escalated privileges.

2) An input validation error exists within the "MrxSmbCscIoctlCloseForCopyChunk()" function in MRXSMB.SYS when handling certain requests. This can be exploited to cause a deadlock, which potentially leads to a DoS, by passing an invalid handle to the function.
