SecurityTracker Alert ID:  1021844
SecurityTracker URL:  http://securitytracker.com/id/1021844
CVE Reference:   CVE-2008-1036   (Links to External Site)
Date:  Mar 12 2009
Impact:   Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in Mac OS X in the processing of certain character encodings. A remote user can bypass content filters. ICU is affected.

The International Components for Unicode (ICU) component does not properly handle certain character encodings.

A remote user can create character sequences that may not appear in the converted output, allowing the remote user to create content that bypasses content filters. This may also allow cross-site scripting attacks.

Impact:   A remote user can create content that may bypass content filters or permit cross-site scripting attacks.
Solution:   Red Hat has released a fix for ICU.

The Red Hat advisory is available at:
