Mozilla has fixed multiple flaws in Firefox, SeaMonkey and Thunderbird that attackers could exploit to bypass security restrictions, crash machines and run malicious code. The issues do not appear to affect the recently-released Firefox 2.0.
According to three advisories Mozilla released Tuesday:
The problems are rated critical by Mozilla and are fixed in Firefox 18.104.22.168, Thunderbird 22.214.171.124 and SeaMonkey 1.0.6.
The issues do not appear to affect the recently released Firefox 2.0, which included a variety of security tweaks and a new anti-phishing feature.
