CVE-2005-0148: Mozilla Thunderbird

Medium severity, CVSS 5.0. EPSS: 1% chance of exploitation in the next 30 days.

Thunderbird before 0.9, when running on Windows systems, uses the default handler when processing javascript: links, which invokes Internet Explorer and may expose the Thunderbird user to vulnerabilities in the version of Internet Explorer that is installed on the user's system. NOTE: since the invocation between multiple products is a common practice, and the vulnerabilities inherent in multi-product interactions are not easily enumerable, this issue might be REJECTED in the future.

Affected products

• Mozilla Thunderbird: version 0.6 only; version 0.7 only; version 0.8 only
