Search engine Google has reportedly issued a patch to mend the security flaw detected by security firm BlueBox which made almost all Android phones vulnerable to hacking .
As revealed earlier by the security firm, Android uses the cryptographic signature as a way to check that an app or program is legitimate and to ensure it has not been tampered with, however, BlueBox found a method of tricking the way Android checks these signatures so that malicious changes to the apps go unnoticed.
According to News.com.au, Google has released a patch to original equipment manufacturers in a bid to address the bug which reportedly affected up to 900 million Android devices since the release of Android 1.6 in 2009.
Google's Android Communications Manager, Gina Scigliano said that there has not been any evidence of exploitation in Google Play or other app stores because of the loophole.
The report said that while the security hole exists, there is no indication that it has yet been exploited and Android users can manually check for system updates through the settings menu or can rely upon their hardware providers for the update.
