TITLE

Apple iOS and OS X Kernel kernel arbitrary code execution vulnerability in privileged context

DESCRIPTION

The kernel in Apple iOS before 9.3.2 and OS X before 10.11.5 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app. Apple Mac OS X is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code, gain sensitive information, cause denial-of-service conditions, bypass security restrictions, and perform unauthorized actions. This may aid in other attacks. Apple Mac OS X 10.9.5, 10.10.5 and 10.11 through 10.11.4 are vulnerable. in the United States. Apple iOS is an operating system developed for mobile devices; OS X El Capitan is a dedicated operating system developed for Mac computers. Kernel is one of the kernel components. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2016-05-16-2 iOS 9.3.2 iOS 9.3.2 is now available and addresses the following: Accessibility Available for: iPhone 4s and later, iPod touch (5th generation) and later, iPad 2 and later Impact: An application may be able to determine kernel memory layout Description: A buffer overflow was addressed through improved size validation.
