Ubuntu Security Notice USN-1842-1
May 29, 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 versions:

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

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.
