The ApiThread function in the firewall service (aka TmPfw.exe) in Trend Micro Network Security Component (NSC) modules, as used in Trend Micro OfficeScan 8.0 SP1 Patch 1 and Internet Security 2007 and 2008 17.0.1224, allows remote attackers to cause a denial of service (service crash) via a packet with a large value in an unspecified size field.

The Trend Micro Personal Firewall service (aka TmPfw.exe) in Trend Micro Network Security Component (NSC) modules, as used in Trend Micro OfficeScan 8.0 SP1 Patch 1 and Internet Security 2007 and 2008 17.0.1224, relies on client-side password protection implemented in the configuration GUI, which allows local users to bypass intended access restrictions and change firewall settings by using a modified client to send crafted packets.

Directory traversal vulnerability in the UpdateAgent function in TmListen.exe in the OfficeScanNT Listener service in the client in Trend Micro OfficeScan 7.3 Patch 4 build 1367 and other builds before 1372, OfficeScan 8.0 SP1 before build 1222, OfficeScan 8.0 SP1 Patch 1 before build 3087, and Worry-Free Business Security 5.0 before build 1220 allows remote attackers to read arbitrary files via directory traversal sequences in an HTTP request. NOTE: some of these details are obtained from third party information.

The CGI modules in the server in Trend Micro OfficeScan 8.0 SP1 before build 2439 and 8.0 SP1 Patch 1 before build 3087 allow remote attackers to cause a denial of service (NULL pointer dereference and child process crash) via crafted HTTP headers, related to the "error handling mechanism."
