  • Apple fixed an issue with the Kernel that may allow malicious application to execute arbitrary code with system privileges.
  • Two issues related to the Lock Screen is fixed in the latest iOS update. If a person has physical access to the iOS device, they may be able to use brute force attack to break the passcode. Next, they can access photos saved in the Photo Library. The brute force attack is possible as the bug allows the attacker to exceed the maximum number of failed passcode attempts. The second bug allows the attacker to view and send photos if you keep the Leave a Message option in FaceTime enabled.
  • A bug in Sandbox Profiles is fixed that allowed malicious application to launch arbitrary binaries on a trusted device.
  • Fixed an issue with Spotlight that caused unnecessary information to be included as part of the initial connection between Spotlight or Safari and the Spotlight Suggestions servers.
  • Fixed an issue in WebKit. If you visit a maliciously crafted website, it may cause unexpected application termination or arbitrary code execution.
