- Published: 2005-01-29 · Updated: 2024-08-07

## Affected

- n/a: version range not reported

## Description

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.
