The kernel in Apple iOS before 10, OS X before 10.12, tvOS before 10, and watchOS before 3 allows attackers to obtain sensitive memory-layout information or cause a denial of service (out-of-bounds read) via a crafted app, a different vulnerability than CVE-2016-4774 and CVE-2016-4776.

Versions of Apple TV earlier than 10.0 are vulnerable to the following issues :

 - A flaw exists in libxml2 that is triggered as certain input is not properly validated.  This may allow a local attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code. (CVE-2016-4658)
 - A flaw exists in FontParser that is triggered during the handling of a specially crafted font file. This may allow a context-dependent attacker to disclose information in process memory. (CVE-2016-4718)
 - An unspecified flaw exists in IOAcceleratorFamily that may allow a context-dependent attacker to disclose arbitrary contents of the memory.  No further details have been provided. (CVE-2016-4725)
 - A flaw exists in IOAcceleratorFamily that is triggered as certain input is not properly validated.  This may allow a local attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code. (CVE-2016-4726)
 - A flaw exists in libxslt that is triggered as certain input is not properly validated.  This may allow a local attacker to corrupt memory and cause a denial of service or potentially execute arbitrary code. (CVE-2016-4738)
 - A flaw exists that is triggered during the handling of a signed disk image.  This may allow a local attacker to gain elevated privileges.  No further details have been provided by the vendor. (CVE-2016-4753)
 - A flaw exists in the kernel that is triggered as the system fails to properly handle locking.  This may allow a remote attacker to cause a denial of service. (CVE-2016-4772)
 - An out-of-bounds read flaw exists in the Kernel that that may allow a local attacker to disclose the contents of memory.  No further details have been provided. (CVE-2016-4773)
