Description:   Multiple vulnerabilities were reported in Apple iOS. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can cause denial of service conditions on the target system. A remote or local user can bypass security restrictions. An application can gain elevated privileges. A remote user can obtain potentially sensitive information on the target system. Apple Safari is affected.

When the target user's Apple Watch is not on the user's wrist, a physically local user can exploit a logic error in Auto Unlock and unlock [CVE-2017-2352].

A remote user can create a specially crafted contact card that, when loaded by the target user, will cause the target application to crash [CVE-2017-2368].

An application can trigger a buffer overflow to execute arbitrary code with kernel privileges [CVE-2017-2370].

An application can trigger a use-after-free memory error to execute arbitrary code with kernel privileges [CVE-2017-2360].

A remote user can create a specially crafted archive that, when unpacked by the target user, will trigger a buffer overflow in libarchive and execute arbitrary code on the target system [CVE-2016-8687].

A remote user can create specially crafted web content that, when loaded by the target user, will trigger a memory initialization error and execute arbitrary code on the target system
[CVE-2017-2355].

A remote user can create specially crafted web content that, when loaded by the target user, will trigger a memory corruption error and execute arbitrary code on the target system [CVE-2017-2354, CVE-2017-2356, CVE-2017-2362, CVE-2017-2373, CVE-2017-2366, CVE-2017-2369].

A remote user can create specially crafted web content that, when loaded by the target user, will open popups [CVE-2017-2371].

A remote user can create specially crafted web content that, when loaded by the target user, will access data from a different domain [CVE-2017-2350, CVE-2017-2363, CVE-2017-2364, CVE-2017-2365].

A physically local user can cause an activation-locked device to present the home screen [CVE-2017-2351].

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A remote user can cause denial of service conditions.

A local user can bypass security controls on the target system.

A remote user can gain elevated privileges on the target system.

A remote user can bypass security controls on the target system.

A remote user can obtain potentially sensitive information on the target system.
