Subject: CVE request: XSS in python paste


Quoting [1]:

> Paste 1.7.4 is released.  The only real change is to paste.httpexceptions, 
> which was using insecure quoting of some parameters and allowed an XSS 
> hole,

> applications using paste.httpexceptions may be effected (especially 
> HTTPNotFound).  WebOb/webob.exc.HTTPNotFound is not affected.
