Descriptions

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.

kio/kio/tcpslavebase.cpp de KDE KSSL de kdelibs en versiones anteriores a la 4.6.1 no verifica apropiadamente que el nombre del servidor sea el mismo que el nombre de domino del subjeto de un certificado X.509, lo que permite a atacantes man-in-the-middle suplantar servidores SSL de su elección a través de un certificado suministrado por una autoridad de certificación legítima para una dirección IP. Una vulnerabilidad distinta a la CVE-2009-2702.
