CVE-2005-0233
HighSummary
The International Domain Name (IDN) support in Firefox 1.0, Camino .8.5, and Mozilla before 1.7.6 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.
Risk Assessment
The risk is that users may be tricked into entering sensitive data on a fake site that appears to be a trusted domain, leading to theft of login credentials or other sensitive information.
Recommendation
It is recommended to immediately update Firefox to version 1.0.1 or later, Mozilla to version 1.7.6 or later, and Camino to version .8.6 or later to eliminate this vulnerability.
