- V3 Apps
The US Computer Emergency Response Team (CERT) has issued a statement urging businesses to install security fixes from Apple, Google and Mozilla.
The three updates refer to various security holes in Apple, Mozilla and Google's services.
The Apple update is the latest designed to fix the slew of Java-based vulnerabilities afflicting Mac OS X customers.
The update aims to secure Java on OS X Lion v10.7 or later, OS X Lion Server v10.7 or later, OS X Mountain Lion 10.8 or later, Mac OS X v10.6.8, and Mac OS X Server v10.6.8.
"These vulnerabilities may allow an attacker to execute arbitrary code. US-CERT encourages users and administrators to review Apple Support Article HT5666 and follow best-practice security policies to determine which updates should be applied," CERT advised users.
The Google Chrome update was designed to fix multiple vulnerabilities, some of which could allow a hacker to bypass the service's in-built security features and mount a denial-of-service attack.
"US CERT encourages users and administrators to review the Google Chrome Release blog entry and update to Chrome 25.0.1364.87," wrote the US CERT.
The Mozilla releases refer to multiple of the company's products including its popular FireFox web browser.
Other products include Firefox ESR 17.0.3Thunderbird 17.0.3, Thunderbird ESR 17.0.3 and SeaMonkey 2.16.
The US CERT warned that if left unpatched businesses would vulnerable to a variety of attacks.
"These vulnerabilities could allow an attacker to execute arbitrary code, bypass security features, or cause a denial-of-service condition," CERT warned.
"US-CERT encourages users and administrators to review the Mozilla Foundation Advisory and apply any necessary updates to help mitigate the risk."
The news will welcomed by all three companies as in the past the US CERT has been less positive about security patches.
Earlier in the year the US CERT issued a statement criticising Oracle, claiming a patch it released to secure Java had not worked.
