CVE-2019-8755

TITLE

plural Apple Updates to product vulnerabilities

DESCRIPTION

A logic issue was addressed with improved restrictions. This issue is fixed in macOS Catalina 10.15. A malicious application may be able to determine kernel memory layout. Apple Has released an update for each product.The expected impact depends on each vulnerability, but can be affected as follows: * information leak * Falsification of information * Arbitrary code execution * Service operation interruption (DoS) * Privilege escalation * Authentication bypass. This vulnerability allows local attackers to escalate privileges on affected installations of Apple macOS. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within AppleIntelCFLGraphicsFramebuffer.kext. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the kernel. Apple macOS Catalina is a set of dedicated operating systems developed by Apple for Mac computers. IOGraphics is one of the input and output graphics components. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2019-10-29-10 Additional information for APPLE-SA-2019-10-07-1 macOS Catalina 10.15 macOS Catalina 10.15 addresses the following: AMD Available for: MacBook (Early 2015 and later), MacBook Air (Mid 2012 and later), MacBook Pro (Mid 2012 and later), Mac mini (Late 2012 and later), iMac (Late 2012 and later), iMac Pro (all models), Mac Pro (Late 2013 and later) Impact: An application may be able to execute arbitrary code with kernel privileges Description: A memory corruption issue was addressed with improved memory handling.
