Vulnerability from variot

An issue was discovered in certain Apple products. macOS before 10.13.2 is affected. The issue involves the "Intel Graphics Driver" component. It allows local users to bypass intended memory-read restrictions or cause a denial of service (out-of-bounds read and system crash). Apple macOS is prone to multiple security vulnerabilities. Attackers can exploit these issues to bypass security restrictions, execute arbitrary code and perform unauthorized action; this may aid in launching further attacks. Apple macOS High Sierra is a dedicated operating system developed by Apple for Mac computers. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512
