Description Jan Lieskovsky 2009-10-20 11:28:12 UTC 
Several cross-site scripting (XSS) flaws were found in the way CUPS web
server interface used to process HTML form(s) content. A remote attacker
could provide a specially-crafted HTML page(s), which once visited, by
a local, unsuspecting user could lead to intended client-side security
mechanisms bypass or, potentially, to injecting of malicious scripts into
web pages, processed by CUPS web interface.

Regression fix

It was reported that upstream patch breaks adding a class using the web interface.  Following patch was proposed and is being reviewed upstream.  It's possible this fix won't make it to upstream 1.4.2.
Comment 11 Tomas Hoger 2009-11-10 07:42:43 UTC 
Now fixed in 1.4.2, which should also contain regression fix mentioned in comment #10:
