A vulnerability has been found and corrected in kdelibs4:

kio/kio/tcpslavebase.cpp in KDE KSSL in kdelibs before 4.6.1 does not
properly verify that the server hostname matches the domain name of
the subject of an X.509 certificate, which allows man-in-the-middle
attackers to spoof arbitrary SSL servers via a certificate issued by
a legitimate Certification Authority for an IP address, a different
vulnerability than CVE-2009-2702 (CVE-2011-1094).

Additionally it was discovered that kdelibs4 for 2009.0 was using an
old private copy of the ca-bundle.crt file containing the root CA
certs, this has now been resolved so that it uses the system wide
and up to date /etc/pki/tls/certs/ca-bundle.crt file last updated
with the MDVSA-2011:068 advisory.

Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:
