USN-1110-1: KDE-Libs vulnerabilities
14 April 2011
An attacker could send crafted input to Konqueror to view sensitive information.
- 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.
The problem can be corrected by updating your system to the following package versions:
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.
