Full Disclosure: Low severity flaw in various applications including KSSL, Rekonq, Arora, Psi IM

[Tim Brown <timb () nth-dimension org uk>]

I recently discovered that various Qt applications including KSSL (the KDE 
class library responsible for SSL negotiation), Rekonq, Arora and Psi IM are 
vulnerable to UI spoofing due to their use of QLabel objects to render 
externally controlled security critical information.  The primary area of 
concern at this time relates to the named applications SSL certificate dialogue 
UI however other similar dialogue boxes may also be vulnerable.

After discussions with Nokia, KDE and the Rekonq developers the following
CVEs have been assigned to this issue:

* KSSL - CVE-2011-3365
* Rekonq - CVE-2011-3366
* Arora - CVE-2011-3367

Note that no CVE has yet been assigned to Psi IM.  Nokia have also
updated the QLabel class section of the Qt documentation to provide
updated security information regarding this issue.
