Google Releases Chrome 22 and Pays Out Nearly $30K in Rewards

Google has released Chrome 22, a major new version of its browser that includes a huge number of security fixes, many of them high-priority vulnerabilities. The company also handed out nearly $30,000 in rewards to security researchers, more than half of it to Sergey Glazunov, who discovered two especially severe bugs that the Chrome security team deemed worthy of special rewards.


Another malicious website has been discovered hosting an exploit for the zero-day vulnerability Internet Explorer patched by Microsoft last week. This site, like the other exploits discovered, targets the defense and space industries, and is dropping an unknown payload, according to Barracuda Labs.

As expected, Microsoft today released a cumulative update for Internet Explorer addressing the zero-day vulnerability in the browser being actively exploited in the wild. Security Update MS 12-063 patches not only the critical remote-execution zero-day, but four other vulnerabilities privately disclosed to Microsoft that are not being exploited.

With tens of thousands camped in line today waiting for the Apple iPhone 5, hackers have already had their hands on the core iOS 6 operating system for some time. Two Dutch hackers managed to successfully beat Apple’s sturdy protections in place, and this week at the EUSecWest conference in Amsterdam presented the first successful hack of a patched iPhone 4S with an exploit that will also work against the new device.

There is a serious vulnerability in the authentication protocol used by some Oracle databases, a flaw that could enable a remote attacker to brute-force a token provided by the server prior to authentication and determine a user’s password. The attacker could then log on as an authenticated user and take unauthorized actions on the database. The researcher who discovered the bug has a tool that can crack some simple passwords in about five hours on a normal PC.

Microsoft announced last night it would issue an out-of-band patch on Friday for a zero-day Internet Explorer vulnerability disclosed earlier this week. In the meantime, Microsoft made a FixIt available on Wednesday that would temporarily mitigate the threat posed by active exploits found in the wild.The out-of-band patch will be available by 1 p.m. ET on Friday, said Yunsun Wee, director of Trustworthy Computing for Microsoft.
