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
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
- Ubuntu 6.06 LTS:
- libqt3-mt 3:3.3.6-1ubuntu6.2
- kdelibs4c2a 4:3.5.2-0ubuntu18.4
- Ubuntu 5.10:
- libqt3-mt 3:3.3.4-8ubuntu5.2
- 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.
