c63b9a944ba7c2935d68a4a420c83a2435da78ca96c29e73e8fb03e625d03496Ubuntu Security Notice 1110-1 - 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. Tim Brown discovered that KDE KHTML did not properly escape URLs from externally generated error pages. An attacker could exploit 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.
e78defb86c69f2ca1bbb9d91a5cec00811d513de3ef5cdfff2e34ffe7feee4cfMandriva Linux Security Advisory 2011-071 - 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. 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.
