CVE reference:CVE-2005-0045


Description:
eEye Digital Security has reported a vulnerability in Microsoft Windows, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error within the SMB client code when handling SMB "Trans" and "Trans2" commands. This can be exploited via a malicious SMB server to cause a buffer overflow by returning specially crafted Transaction response data to a vulnerable system.

Successful exploitation allows execution of arbitrary code.

Solution:
Apply patches.
