| Detailed Description |
The hotfix (KB914389) for 'Vulnerability in Server Message Block' has not been applied. Microsoft Windows 2000, Windows XP, and Windows Server 2003 are vulnerable to two vulnerabilities, which could be exploited by an attacker to obtain elevated privileges or cause a denial of service.
1) The first flaw is due to a buffer overflow error in the "MrxSmbCscIoctlOpenForCopyChunk()" within the Client Side Caching (CSCDLL.DLL) and the Server Message Block Redirector Driver (MRXSMB.SYS), which could be exploited by a local attacker to execute arbitrary commands with SYSTEM privileges.
2) The second issue is due to an access validation error in the "MrxSmbCscIoctlCloseForCopyChunk()" within the Client Side Caching (CSCDLL.DLL) and the Server Message Block Redirector Driver (MRXSMB.SYS), which could be exploited by a remote attacker to cause an affected system to stop responding.
* Note: This check requires an account with Guest or upper privileges which can access the registry of the remote host to scan. Absence of these condition will result in the check not being performed and a False Negative for all vulnerable hosts.
