USN-452-1: KDE library vulnerability

Ubuntu Security Notice USN-452-1

11th April, 2007

kdelibs, qt-x11-free vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 6.10
  • Ubuntu 6.06 LTS
  • Ubuntu 5.10

Details

The Qt library did not correctly handle truncated UTF8 strings, which
could cause some applications to incorrectly filter malicious strings.
If a Konqueror user were tricked into visiting a web site containing
specially crafted strings, normal XSS prevention could be bypassed
allowing a remote attacker to steal confidential data.

The problem can be corrected by updating your system to the following package version:

Ubuntu 6.10:
libqt3-mt 3:3.3.6-3ubuntu3.1
kdelibs4c2a 4:3.5.5-0ubuntu3.4

kdelibs4c2 4:3.4.3-0ubuntu2.4

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

After a standard system upgrade you need to restart your session or
reboot your computer to effect the necessary changes.
