The issue allows remote attackers to bypass the Same Origin Policy via a crafted fragment identifier in the SRC attribute of an IFRAME element. This leads to insufficient restrictions on link-color information after a document is resized.

The issue allows user-assisted remote attackers to execute arbitrary JavaScript code with chrome privileges via a `javascript:` URL that is later interpreted in the `about:sessionrestore` context. This is possible because the software does not properly restrict setting the home page through the dragging of a URL to the home button.

Name of the Vulnerable Software and Affected Versions: Firefox version 1.0.3 Description: The issue allows remote attackers to execute arbitrary Javascript in other domains. This is achieved by using an IFRAME and causing the browser to navigate to a previous javascript: URL, which can lead to arbitrary code execution. Recommendations: For Firefox version 1.0.3, update to a newer version to mitigate the risk.

Name of the Vulnerable Software and Affected Versions: Firefox version 1.0.3 Description: The issue allows remote web sites on the browser's whitelist to execute arbitrary Javascript with chrome privileges. This can lead to arbitrary code execution on the system when combined with other vulnerabilities. The exploitation can be demonstrated using a javascript: URL as the package icon and a cross-site scripting (XSS) attack on a vulnerable whitelist site. Recommendations: For Firefox version 1.0.3, consider restricting access to the `install` function until a patch is available. As a temporary workaround, avoid using the `javascript:` URL scheme for package icons to minimize the risk of exploitation.
