Apple has released an out-of-cycle patch for vulnerabilities in its iOS mobile operating system being exploited for the latest software to jailbreak iPhones and iPads.
The move comes less than a fortnight after Germany's Federal Office for Information Security and several independent security researchers highlighted flaws in Apple's iOS version 4.3.3 for the iPhone, iPad and iPod. Cyber criminals can exploit the vulnerability to infect the mobile devices with malware without the user's knowledge.
JailbreakMe 3.0, designed to allow Apple device users to run software other than that dictated by Apple, exploits two of the vulnerabilities fixed in the update, which upgrades the iOS to version 4.3.4.
Although the next scheduled update of iOS is in September, security experts said Apple should not delay in releasing a security update out-of-cycle, because of the risks of leaving the flaws unpatched.
After the flaws were highlighted by the German security agency, Graham Cluley, senior technology consultant at Sophos, said leaving a security hole like this open was inviting malicious hackers to exploit it.
