![]() If you are a user of Firefox you may have noticed that a new version is available already, bringing the version of Firefox on the stable channel to 19.0.2 The patch is a direct result of the Pwn2own exploit that was used by Vupen to exploit the Firefox web browser on Windows. Both ASLR and DEP are part of the Windows operating system that help protect the system's memory against exploits. As far as Firefox goes, security firm VUPEN managed to exploit the browser using a "use-after-free" memory flaw that it combined with an ASLR/DEP memory exploit. This year, all three major browsers - Internet Explorer, Google Chrome and Mozilla Firefox -Â were successfully exploited by security experts. Winners of the contest not only get prize money for their efforts, but can also keep the devices they successfully exploited. The Pwn2own security challenge is an annual competition in which hackers and security experts from all over the world try to beat the protection of software and mobile devices.
