Secunia researchers detected numerous security vulnerabilities in the Mozilla Firefox 2.0x Web browser, many of which enable malicious attackers to hack into vulnerable systems and either shut down or take complete control of a user"s computer. Researchers at Secunia, a Copenhagen, Denmark-based security company specializing in vulnerability assessment and management, issued a security advisory Wednesday, warning users of multiple errors they deemed "highly critical."
If exploited, the critical vulnerabilities could potentially allow remote attackers to conduct cross-site scripting and spoofing attacks, bypass security restrictions, disclose sensitive or system information, potentially compromise a user"s system, access a user"s system or launch a denial of service attack, according to the advisory.
