Microsoft Windows Server Driver Mailslot Remote Heap Buffer Overflow Vulnerability

Risk

High

Date Discovered

July 11, 2006

Description

Microsoft Windows Server driver is prone to a remote heap buffer-overflow vulnerability. This issue is due to a failure of the software to properly bounds check user-supplied input prior to copying it to an insufficiently-sized memory buffer. Exploiting this issue allows anonymous, remote attackers to execute arbitrary machine code in the context of the affected driver. This facilitates the complete compromise of affected computers. Microsoft Windows XP SP2 and Microsoft Windows Server 2003 SP1 are not vulnerable to this issue in their default configuration.

Recommendations

Block external access at the network boundary, unless external parties require service.

Allow only trusted hosts and networks to connect to TCP port 445 on computers running the affected software. This will limit the potential for remote attackers to exploit this issue.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploitation attempts or activity that results from successful exploitation.

Implement multiple redundant layers of security.

Various memory-protection schemes (such as non-executable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.
Microsoft has released an advisory along with fixes to address this issue. New information regarding this vulnerability suggests that the fixes listed in this BID may be incomplete. Symantec has not confirmed this.
