USN-1248-1: KDE-Libs vulnerability | Ubuntu security notices

Packages

kde4libs - KDE 4 core applications and libraries

Details

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.
