CVE-2016-4773

TITLE

plural Apple Vulnerability to obtain important memory layout information in the product kernel

DESCRIPTION

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. plural Apple In the product kernel, important memory layout information is obtained or service operation is interrupted ( Read out of bounds ) There are vulnerabilities that are put into a state. This vulnerability CVE-2016-4774 and CVE-2016-4776 Is a different vulnerability. Supplementary information : CWE Vulnerability type by CWE-125: Out-of-bounds Read ( Read out of bounds ) Has been identified. Apple iOS, tvOS,MacOS and watchOS are prone to multiple security vulnerabilities. Attackers can exploit these issues to bypass security restrictions, obtain sensitive information, execute arbitrary code, cause a denial-of-service condition, perform unauthorized actions and gain system privileges; this may aid in launching further attacks. Versions prior to iOS 10, watchOS 3, MacOS 10.12, and tvOS 10 are vulnerable. Apple iOS, OS X, tvOS, and watchOS are all products of the American company Apple (Apple). Apple iOS is an operating system developed for mobile devices; OS X is a dedicated operating system developed for Mac computers; tvOS is a smart TV operating system; watchOS is a smart watch operating system. Kernel is one of the kernel components. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2016-09-20-5 watchOS 3 The watchOS 3 advisory has been updated to include additional entries as noted below.
