Ubuntu Security Notice USN-1842-1

29th May, 2013

kde4libs vulnerability

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

  • Ubuntu 13.04
  • Ubuntu 12.10
  • Ubuntu 12.04 LTS

Summary

KDE-Libs could be made to expose web credentials.

Software description

  • kde4libs - KDE 4 core applications and libraries

Details

It was discovered that KIO would sometimes display web authentication
credentials under certain error conditions. If a user were tricked into
opening a specially crafted web page, an attacker could potentially exploit
this to expose confidential information.

Update instructions

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

Ubuntu 13.04:
libkio5 4:4.10.2-0ubuntu2.2
Ubuntu 12.10:
libkio5 4:4.9.5-0ubuntu0.2
Ubuntu 12.04 LTS:
libkio5 4:4.8.5-0ubuntu0.2

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

After a standard system update you need to restart any applications that
use KIO from KDE-Libs, such as Konqueror, to make all the necessary changes.
