Cisco Cisco Email Security Appliance C370D

Persistent cookies stored on the user’s hard disk included a session identifier and 
whether or not the user was logged in. The Email Security appliance web user 
interface now uses temporary (session) cookies for this information, which do not 
present the same risk.

Fixed an issue where a message filter designed to modify message headers did not 
modify structured message headers such as To: and From: correctly. Mail user agents 
like Outlook, Thunderbird, Gmail, and Yahoo Mail could not decode these headers. 
This issue has been resolved.

Previously, an LDAP masquerade query would not be able to process a message with 
a non-English “To:” header where the email address is also encoded and does not 
conform to RFC 2047. The message would get stuck in the queue. This issue has been 
resolved. Now, the appliance decodes and re-encodes a non-compliant To: header and 
performs the correct LDAP masquerade query.

Fixed: PDF with no document open password triggers attachment-protected rule 
in message filter 

If a message filter was set up to catch messages with attachments that require a 
password in order to open them, messages with PDF attachments that did not include 
password protection, but may have included other restrictions, were caught by the 
filter. This no longer occurs.

The DigiNotar blacklist solution added in the previous 7.5.1 hot patch contained a 
defect that resulted in the email process restarting or becoming unresponsive due to 
certain types of TLS traffic. This issue has been resolved and the email process errors 
no longer occurs.
