CAN-2004-1036 Cross Site Scripting in encoded text
Last modified: 2007-11-30 17:10:54 EST
There is a cross site scripting issue in the decoding of encoded text
in certain headers. SquirrelMail correctly decodes the specially
crafted header, but doesn't sanitize the decoded strings.
This issue should also affect FC2.
Attachment 106907 [details] contains the fix for this issue.
Updates for FC2 and FC3 have been issued.
