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

Summary

An attacker could send crafted input to Konqueror to view sensitive

information.

Software Description:

- kde4libs: KDE 4 core applications

Details:

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.
