"Tim Brown discovered that KSSL in KDE-Libs did not properly perform
input validation when displaying the common name (CN) for an SSL
certificate. An attacker could exploit this to spoof the common name
which could be used in an attack to trick the user into accepting a
fraudulent certificate. This issue only affected Ubuntu 10.04 LTS and
Ubuntu 10.10. (CVE-2011-3365)

It was discovered that KIO in KDE-Libs did not properly perform input
validation during proxy authentication. An attacker could exploit this
to modify displaying of the realm and proxy URL.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
