High severity, CVSS 7.5. EPSS: 20.4% chance of exploitation in the next 30 days.

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.

• Omnigroup Omniweb: version 5 only
