Cisco Cisco Email Security Appliance C670

The following issues have been fixed in the AsyncOS 7.1 for Email release.

67002

Previously, entering an invalid regular expression for a RSA Email DLP policy caused 
an application fault that halted DLP scanning even if the regular expression was later 
corrected. While the AsyncOS GUI validates regular expressions, it may not catch all 
errors. There were two known regular expression errors that could cause this 
application fault:

the repeat construct, which is represented as brackets (

{}

), if the brackets are 

empty or contain something other than a single number or two numbers separated 
by a comma, and

a regular expression begins or ends with the “or” construct, which is represented 
as a vertical bar (

|

).

This issue has been resolved. The AsyncOS GUI now tests for the above regular 
expression errors.

Previously, the DLP Matched Content tab on the Message Tracking Details page 
erroneously displays masking backslashes preceding single quotation marks in 
content matching classifiers. For example, 

"b'lad"e '''"2"

' appears as 

"b\'lad"e\'\'\'"2"\'

. This issue has been resolved.

55874

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

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.
