Description: NSFocus Security Team has reported a vulnerability in various RealSecure/BlackICE products, which can be exploited by malicious people to cause a DoS (Denial of Service). The vulnerability is caused due to an error in the detection of the MailSlot buffer overflow vulnerability (MS06-035) and can be exploited to cause an infinite loop by sending a specially crafted SMB MailSlot packet. Successful exploitation causes the application or system to stop responding. Solution: Update to a fixed version (see vendor advisory for details). Provided and/or discovered by: Chen Qing, NSFocus Security Team.
