Buffer overflow in the web console in F-Secure Anti-Virus for Microsoft Exchange 6.40, and Internet Gatekeeper 6.40 through 6.42 and 6.50 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown attack vectors. NOTE: By default, the connections are only allowed from the local host.

Multiple F-Secure Anti-Virus products and versions for Windows and Linux, including Anti-Virus for Windows Servers 5.52 and earlier, Internet Security 2004, 2005 and 2006, and Anti-Virus for Linux Servers 4.64 and earlier, allow remote attackers to hide arbitrary files and data via malformed (1) RAR and (2) ZIP archives, which are not properly scanned.

Buffer overflow in multiple F-Secure Anti-Virus products and versions for Windows and Linux, including Anti-Virus for Windows Servers 5.52 and earlier, Internet Security 2004, 2005 and 2006, and Anti-Virus for Linux Servers 4.64 and earlier, allows remote attackers to execute arbitrary code via crafted ZIP archives.

Directory traversal vulnerability in F-Secure Anti-Virus for Microsoft Exchange 6.40 and Internet Gatekeeper 6.40 to 6.42 allows limited remote attackers to bypass Web Console authentication and read files.

Multiple interpretation error in various F-Secure Anti-Virus products, including Workstation 5.43 and earlier, Windows Servers 5.50 and earlier, MIMEsweeper 5.50 and earlier, Anti-Virus for Linux Servers and Gateways 4.61 and earlier, and other products, allows remote attackers to bypass antivirus protection via a compressed file with both local and global headers set to zero, which does not prevent the compressed file from being opened on the target system.
