CVE-2011-1094

kdelibs < 4.6.1 - Man-in-the-Middle Attack via X.509 Certificate Hostname Mismatch

Title source: llm
STIX 2.1

Description

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.
