========================================================================== Ubuntu Security Notice USN-1110-1 April 14, 2011

kde4libs vulnerabilities

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

  • Ubuntu 10.10
  • Ubuntu 10.04 LTS
  • Ubuntu 9.10


An attacker could send crafted input to Konqueror to view sensitive information.

Software Description: - kde4libs: KDE 4 core applications


It was discovered that KDE KSSL did not properly verify X.509 certificates when the certificate was issued for an IP address. An attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. (CVE-2011-1094)

Tim Brown discovered that KDE KHTML did not properly escape URLs from externally generated error pages. An attacker could expoit this to conduct cross-site scripting attacks. With cross-site scripting vulnerabilities, if a user were tricked into viewing server output during a crafted server request, a remote attacker could exploit this to modify the contents, or steal confidential data (such as passwords), within the same domain. (CVE-2011-1168)

Update instructions:

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

Ubuntu 10.10: libkhtml5 4:4.5.1-0ubuntu8.1 libkio5 4:4.5.1-0ubuntu8.1

Ubuntu 10.04 LTS: kdelibs5 4:4.4.5-0ubuntu1.1

Ubuntu 9.10: kdelibs5 4:4.3.2-0ubuntu7.3

After a standard system update you need to restart any applications that use KSSL or KHTML, such as Konqueror, to make all the necessary changes.
