*SECURITY FIX ISSUED FOR WATCHGUARD FIREWALL WatchGuard Technologies last week released hotfixes for vulnerabilities affecting its Vclass software. Legacy RSSA appliances running the current version of Vclass software and legacy RSSA appliances that haven't upgraded to Vclass software are also affected. The vulnerabilities originate in the command line interface (CLI) and include a format strings vulnerability in the password validation code that could allow an attacker to gain root access. WatchGuard recommends "that all affected customers download, test and install the appropriate version of this hotfix as soon as is practical." The company also recommends verifying that only trusted hosts can connect to the CLI.

Open source software has being targeted by malware writers more often as these products gain popularity. Network Associates' Anti-virus Emergency Response Team (AVERT) detected "over 170 viruses and Trojans for Linux, as well as an additional 30 Unix shell scripts." Slapper worm variants, which affect Linux run machines, have infected 2,500 (Slapper C) and 19,200 (Slapper B) machines. It is estimated that Linux use has grown 30 percent per year, and as popularity grows, so will the number of malicious codes released to target these systems. Experts also fear that hybrid attacks, which use a variety of attacks to affect a number of different operating systems.

A new computer virus was discovered on September 30, 2002 that attempts to spread using an e-mail masquerading as a Microsoft security patch. The e-mail urges recipients to run an attachment that appears to be a fix for flaws in Microsoft's Internet Explorer web browser and Outlook e-mail software. The attachment is in fact a virus. This form of deception is a common technique to facilitate the spread of malware.

While it is well known that Microsoft Word is vulnerable to "malevolent macros and document viruses", it could also allow an attacker access to personal files stored on a vulnerable machine in more subtle ways. Exploits using a Word feature called field codes could hijack multiple files if the attacker knows their absolute path on the drive. Several proof of concept exploits using field codes have already been developed.
