Apple Patches

Apple's new mobile operating system, iOS 5.1, not only includes a number of new features, but also a large list of security relavant patches. Eventually, a link to the patches will be listed on Apple's security update page (

iOS fixes the latest passcode lock bypass (CVE-2012-0644). In addition, a number of Safari and Webkit issues are fixed. In addition, code execution issues are fixed in the HFS subsystem (exploitable by mounting a corrupt disk), libresolv, and VPN configuration.
