Ubuntu 10.04 LTS / 10.10 / 11.04 : kde4libs vulnerability (USN-1248-1)

medium Nessus Plugin ID 56647

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Solution

Update the affected kdelibs5 and / or libkio5 packages.
