High
Published: Translated: NVD NIST

Summary

Mozilla Firefox 1.0.7 and 1.5.0.1 may crash (denial of service) when viewing the page source of an HTML tag with a large number of script event handlers like onload and onmouseover. Red Hat and Mozilla disputed this issue, suggesting it may be caused by the IE Tab extension rather than Firefox itself.

Risk Assessment

The risk to the organization is low as the vulnerability is disputed by the vendor and may be caused by an extension, not the browser itself. If confirmed, an attacker could crash the user's browser, leading to a temporary denial of service.

Recommendation

It is recommended to update Firefox to the latest stable version and avoid using unofficial extensions like IE Tab that may introduce additional vulnerabilities.

Original NVD description (English source)

Mozilla Firefox 1.0.7 and 1.5.0.1 allows remote attackers to cause a denial of service (crash) via an HTML tag with a large number of script action handlers such as onload and onmouseover, which triggers the crash when the user views the page source. NOTE: Red Hat has disputed this issue, suggesting that "It is likely the reporter was running the IE Tab extension," and Mozilla also confirmed that this is not an issue in Firefox itself
