ISS BlackICE flaw revealed
BlackICE Server Protect 3.6cno and below are vulnerable to a medium-level threat that could allow any trusted or local unprivileged user to remotely remove or modify the BlackICE firewall rule set, according to researchers. The flaw's discoverers recommend removing The EveryoneFull Control ACL from the blackice.ini, firewall.ini, protect.ini and sigs.ini files. Before doing so, ensure that administrators and system have full control. Backup the blackice.ini, firewall.ini, protect.ini and sigs.ini before each update. And after using UpdateBIDServer.exe, validate the permissions because they are always reset to the default.

NGSEC disputes iDefense claims of flaw in StackDefender
Madrid-based Next Generation Security (NGSEC) is disputing reports of a vulnerability in its StackDefender product by Reston, Va.-based security firm iDefense. Earlier, iDefense reported that NGSEC's intrusion prevention system for Win32 platforms could be exploited by an attacker who specifies an invalid address for 'ObjectAttributes' and can crash a system. NGSEC said testing to overflow a buffer in order to overwrite a pointer pointing to a read-only region and saying StackDefender is not working, is like testing a firewall by not sending packets to it and claiming it is not blocking any packet. "Based on our tests, StackDefender prevents the execution of code in stack, heap, and every user-writeable memory region," according to a statement.
