Mozilla fixes ten critical vulnerabilities in Firefox 6

Mozilla has patched vulnerabilities deemed “critical” and “high risk” in Firefox, several of which could lead to remote code execution by hackers.

Fixed Mozilla vulnerabilities related to memory management, heap overflows and unsigned scripts into Firefox 6 – published August 17. The latest version has been released only two months after Firefox 5, with 1,300 changes.

Operated, several of the flaws could allow an attacker to run code if the user accesses a malicious site.

Mozilla also has four memory leaks patched in the browser engine used in Firefox 4, 5 and other Mozilla products that use the same engine.

Another critical error sign code allows JavaScript to execute a script within a JAR file signed with the authority and identity of that file. The memory corruption errors generated under certain circumstances. Other critical flaws allow unsigned Java code to execute a script within a JAR file with the permissions and identity of that file.

Mozilla has adopted a new release schedule for this year for the web browser Firefox which receives security updates and improvements every six weeks. The aim is to continuous improvement and that updates and changes easier. Under the new Firefox update schedule will be released October 7 and will include improvements to the JavaScript engine and a lower memory usage
