CVE-2011-1094: Red Hat Kdelibs

Medium severity, CVSS 4.3. EPSS: 1% chance of exploitation in the next 30 days.

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.

Affected products

• Red Hat Kdelibs: up to and including 4.6; version 3.5.2 only; version 3.5.9 only; version 3.5.10 only
