Germany's Federal Office for Information Security has doled out an official warning about potential security issues that might affect a number of Apple devices running on Apple iOS mobile platform.
The entity, which at the beginning of the year advised Germans to look for an alternative web browser to Microsoft's Internet Explorer, confirmed that Apple's OS had two "critical weak points" with no solutions in sight, in other words, zero-day vulnerabilities.
The warning (in German here), says that the vulnerability affects iPhone OS v3.1.2 to 4.0.1, iPad version 3.2 and 3.2.1 and iOS for the iPod touch version 3.1.2 and 4.0. The body, which advises the German government on IT security, also said that it is possible that other versions of the iOS are also affected by this vulnerability.
The Federal Office for Information Security advises against opening PDF document on mobile devices and refrain from opening PDF documents from search engines altogether.
The FOIS highlighted the threat that a specially crafted attack could have in the corporate or business environment where the iPhone is extensively used.
