Description Preview

Apple Safari version 2.0.3 could be exploited by a remote attacker through HTML content containing a TABLE tag with an abnormally large CELLSPACING attribute. Processing this input triggers an error in KWQListIteratorImpl::KWQListIteratorImpl, potentially allowing a denial of service and, in some cases, the execution of arbitrary code on the affected system.

Overview

This vulnerability affects Safari 2.0.3 and allows remote attackers to cause a denial of service and possibly execute arbitrary code by supplying a crafted TABLE element with an excessively large CELLSPACING attribute. The flaw manifests when Safari processes the malformed HTML, leading to an error in KWQListIteratorImpl::KWQListIteratorImpl. The issue was disclosed publicly in 2006 and is documented across multiple advisories and references.

Remediation

  • Update Apple Safari to the latest available version that contains security fixes. Apply any accompanying macOS updates that include browser security patches.
  • Ensure the operating system and all software are configured to receive automatic security updates and verify that updates are installed promptly.
  • If an immediate update is not feasible, minimize exposure by avoiding visits to untrusted or suspicious websites and consider using a safer browsing environment until patches are applied.
  • As a defense-in-depth measure, consider enabling security features that reduce web content impact and, where appropriate, limit or disable features that may be exploited by malformed HTML (e.g., use of JavaScript is generally discouraged for untrusted content, though this may affect usability).
