Mozilla Firefox Code Execution and Security Bypass Vulnerabilities

Multiple vulnerabilities have been identified in Mozilla Firefox, which could be exploited by attackers to manipulate certain data, disclose sensitive information or compromise a vulnerable system.

1. Due to an error when handling a SOCKS5 proxy reply containing an overly long DNS name, which could be exploited to corrupt subsequent data stream in the response.

2. Due to a spoofing issue when handling "window.open()" calls.

3. Due to memory corruption errors in the JavaScript and browser engines when parsing malformed data, which could be exploited by attackers to crash a vulnerable application or execute arbitrary code.

4. Due to a broken functionality that the window's global object receiving an incorrect security wrapper on pages that had a "Link:" HTTP header when an add-on implementing a Content Policy in JavaScript was installed, which could allow arbitrary JavaScript execution with chrome privileges.
