Cisco Cisco Email Security Appliance C380

Previously, an application fault occurred when switching between different 
cluster levels on the Encryption Profile page in the GUI. This issue has been 
resolved.

Fixed: Corrupted Uuencoded Content Results in Warning and Skipped Filters 
[Defect ID: 37164]

Previously, a message with a corrupted uuencoded attachment caused the 
Email Security appliance to skip message filters processing and record a 
warning in the mail logs. This issue has been resolved. Now, the appliance 
applies filters to messages with corrupted uuencoded content. 

The following list describes known issues in this release of AsyncOS for Email.

Sophos Anti-Virus Unable to Scan PDFs with Large Cross-Reference Tables 
[Defect ID: 68899]

The most recent Sophos anti-virus scanning engine imposes a maximum limit 
to the number of entries in a PDF’s cross-reference tables to avoid malformed 
files from using too much memory. The scanning engine returns 
“unscannable” for PDFs that exceed the maximum limit even if they are not 
malformed. Cisco IronPort is working with Sophos to resolve this issue in a 
future Sophos engine update.

Cannot Save Regional Settings for IronPort Anti-Spam and IMS for Clustered 
Appliance [Defect ID: 67341]

You cannot save changes to the Regional Settings for IronPort Ant-Spam or 
IronPort Intelligent Multi-Scan via the GUI when a clustered Email Security 
appliance is in cluster or group mode. Workaround: Set the Regional Settings 
for IronPort Anti-Spam or IMS using the CLI instead of the GUI.
