CVE-2009-2702

KDE KSSL in kdelibs 3.5.4, 4.2.4, and 4.3 - Certificate Validation Bypass via Null Byte in Subject Alternative Name

Title source: llm
STIX 2.1

Description

KDE KSSL in kdelibs 3.5.4, 4.2.4, and 4.3 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408.
