The Mozilla Foundation has released multiple security advisories to address vulnerabilities in Mozilla Firefox, Thunderbird, and SeaMonkey. Exploitation of these vulnerabilities may allow a remote, unauthenticated attacker to execute arbitrary code or bypass security restrictions.
US-CERT encourages users and administrators to review the Mozilla Foundation security advisories. Firefox users may upgrade to version 3.0.18, 3.5.8, or 3.6 to help mitigate the risks. Thunderbird users should upgrade to version 3.0.2, and SeaMonkey users should upgrade to version 2.0.3 once those updates are released by the vendor.
