Apple and Google have issued security fixes for several vunerabilities discovered by researchers, and have urged users and administrators to update their systems accordingly.
Google's update addresses seven vulnerabilities in the Chrome browser, six rated as 'high' security risks and one as a 'medium' risk.
None of the seven flaws is listed as 'critical', the highest of Google's Chrome vulnerability threat levels.
Google said that it will pay out cash rewards ranging from $500 to $1,000 to the researchers who discovered the vulnerabilities. None of the flaws qualified for the company's $3,113.70 top prize.
Apple, meanwhile, is addressing 11 vulnerabilities in Java for OS X 10.5 and 10.6. Among the patched flaws are vulnerabilities which could allow an attacker to remotely execute code on a targeted system.
No other platforms are affected by the Apple update.
The Java fix comes just days after Apple issued a general update for its Snow Leopard operating system which included multiple security fixes.
Users can obtain the update through the OS X Software Update tool or by visiting Apple's support downloads site.
