CWmike writes: With Monday's iOS 4 upgrade, Apple patched a record 65 vulnerabilities in the iPhone, more than half of them critical. However, the first-generation iPhone and iPod Touch, as well as the much newer iPad, may have been left vulnerable to some or all of the 65 bugs. iOS 4 cannot be installed on 2007's iPhone and iPod Touch, and the upgrade is not slated to reach iPad owners until this fall. The bug count is a record for Apple's iPhone, surpassing the previous high mark of 46 vulnerabilities patched last summer with iPhone OS 3.0. Formerly known as iPhone OS 4, iOS 4 included 35 bugs, or 54% of the total, that were tagged with the phrase 'arbitrary code execution," Apple's way of saying the vulnerability is critical and could be used to hijack an iPhone or iPod Touch. It's unclear how many, if any, of the vulnerabilities affect Apple's iPad. Although the iPad isn't slated to receive the iOS 4 update until sometime this fall, the media tablet runs an interim version of the operating system, dubbed iPhone 3.2, that followed the February iPhone 3.1.3 security update. It's possible that some of the bugs patched Monday were fixed by Apple before it launched the iPad in early April. But according to the CVE database (Common Vulnerabilities & Exposures), it's likely that many of the flaws fixed on Monday still exist in the iPad's iPhone 3.2 operating system.
