Critical Vulnerability In Google Chrome Patched


Google has released a new version of Google Chrome released that fixes four vulnerabilities, including a critical vulnerability that the underlying operating system in the worst case could be full. Visiting a malicious or hacked website or see getting an infected ad would have been sufficient in this case.

This kind of critical vulnerabilities are rare in Google Chrome. Last year there were only three of these types of leaks reported in Chrome. Critical vulnerabilities allow an attacker to run arbitrary code on the computer can perform, such as installing malware, come because of the sandbox security in the browser rare. In addition to a leak in the browser must also be a leak in the sandbox are found to execute code on the underlying system.

The vulnerability, which consists of various bugs, was reported by an anonymous security researcher. Google rewarded the researcher before with a total of almost $ 30,000. Besides this leak is also a vulnerability patched during the Pwn2Own contest was demonstrated. Researcher Jung Hoon Lee aka "lokihardt" succeeded during the event in order to execute arbitrary code via various vulnerabilities. Update to Chrome 41.0.2272.118 will happen automatically in most cases.

Also, Google Chrome And Safari Hacked During Competition


After Internet Explorer and Firefox during the Pwn2Own contest in Vancouver also Google Chrome and Safari hacked. The Pwn2Own contest is an annual event organized at the CanSecWest conference where researchers and the safety of popular browsers, and browser plug-ins can be tested. During the first day of the event there were leaks in Adobe Flash Player (3) Adobe Reader (3) Windows (3) Internet Explorer 11 (2) and Firefox (2) demonstrated.

During the second day were 11 Internet Explorer and Firefox again to believe. Additionally died also Google Chrome and Safari on Mac OS X. The attacks on IE11, Chrome and Safari were demonstrated by Jung Hoon Lee aka "lokihardt". The researcher was awarded a total of $ 225,000. Most of it, $ 110,000, Lee received because of his attack on Google Chrome.The researcher also showed also two Windows Leaks which he could execute code with system privileges.

In total there are 21 vulnerabilities demonstrated during the two days for which no security updates are available from the respective vendors. Microsoft leads with five vulnerabilities in Windows and four leaks in IE11 the list. Details on the vulnerabilities found will be made public until the updates are available.

Prize For Hacking Chrome During Pwn2Own


During a hacker contest next month in Vancouver held hackers and researchers can win the grand prize by hacking Google Chrome. Who a vulnerability in Google's browser on Windows 8.1 knows how to find can earn $ 75,000.

This is more than for leaks is offered in other browsers. The game in question is the annual Pwn2Own contest, which takes place during the CanSecWest conference. Every year, researchers and hackers at the event to test the security of browsers.After the prize for Google Chrome follows Internet Explore 11 where a reward of $ 65,000 to be offered. Apple Safari on Mac OS X Yosemite follows with $ 50,000 in the third. Finally provides a successful hack of Mozilla Firefox at $ 30,000.

Besides the four browsers will be tested also the security of Adobe Reader and Adobe Flash Player. A successful attack on both programs make $ 60,000 on. This year, the difficulty for participants is much higher than previous years because the exploits that should be developed with Microsoft's free security tool EMET works.

The Enhanced Mitigation Experience Toolkit (EMET) is precisely designed to neutralize the effect of exploits. As a result, researchers now take two hurdles. Researchers who through their exploits on a Windows computer code with SYSTEM privileges can perform get an extra $ 25,000 reward. In addition, Google will in the case of a Chrome hack pay an additional reward of $ 10,000. Pwn2Own will take place on 18th and 19th March.
