Detailsinfo

A vulnerability was found in KDE Konqueror 3.2.1 (Web Browser). It has been declared as problematic. Affected by this vulnerability is an unknown functionality of the component IDN International Domain Name Handler. The manipulation with an unknown input leads to a authentication spoofing vulnerability. The CWE definition for the vulnerability is CWE-290. This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks. As an impact it is known to affect integrity. The summary by CVE is:

The International Domain Name (IDN) support in Konqueror 3.2.1 on KDE 3.2.1 allows remote attackers to spoof domain names using punycode encoded domain names that are decoded in URLs and SSL certificates in a way that uses homograph characters from other character sets, which facilitates phishing attacks.
