========================================================================== F-Secure Anti-Virus for Microsoft Exchange Version 6.30 and 6.31 Post-Release Fix Copyright (c) 1993-2004 F-Secure Corporation. All Rights Reserved. ========================================================================== INDEX o Summary o More Information o How to Apply SUMMARY This post-release fix is for the following products/versions: o F-Secure Anti-Virus for Microsoft Exchange 6.30 o F-Secure Anti-Virus for Microsoft Exchange 6.30 Service Release 1 o F-Secure Anti-Virus for Microsoft Exchange 6.31 This post-release version includes the following fixes: o CTS#36132 Password protected files in ZIP archives may pass detection o CTS#36151 Nested archives not dropped when marked as unsafe TECHNICAL DETAILS This hotfix improves the handling of password protected and nested archive files. Prior to this hotfix, some password protected files were not detected inside a ZIP archive. After installing this hotfix the product detects those correctly. Nested archive files were not quarantined even if F-Secure Content Scanner Server was configured to report them as "unsafe". After applying this hotfix the password protected files and nested archives will be quarantined in the "infect" quarantine directory, if quarantining is turned on in the product settings. It should be noted that the settings related to the nested archives and password protected files in ZIP archives also affect the manual scanning. If the product is configured to treat the password protected or nested archives as unsafe, manual scanning will remove those from the Microsoft Exchange Server. Installing this hotfix requires a reboot. F-Secure recommends all the F-Secure Anti-Virus for Microsoft Exchange users to apply this hotfix.
