- kde4libs - KDE 4 core applications and libraries

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.
The problem can be corrected by updating your system to the following package versions:
After a standard system update you need to restart any applications that
use KSSL and KIO, such as Konqueror and Rekong, to make all the necessary
