TITLE

plural Apple Updates to product vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2019-003317

DESCRIPTION

A memory corruption issue was addressed with improved memory handling. This issue is fixed in macOS Mojave 10.14.5. An application may be able to execute arbitrary code with system privileges. Apple Has released an update for each product.The expected impact depends on each vulnerability, but can be affected as follows: * Insufficient access restrictions * Privilege escalation * Service operation interruption (DoS) * Sandbox avoidance * Information falsification * information leak * Arbitrary code execution. The issue results from the lack of validating the existence of an object prior to performing operations on the object. This vulnerability allows local attackers to escalate privileges on vulnerable 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 the discard_StretchTex2Tex method of the AMDRadeonX4000_AMDSIGLContext class. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated data structure. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges to the level of the kernel. Apple macOS Mojave is a set of dedicated operating systems developed by Apple for Mac computers. AMD is one of the components used in AMD products. A resource management error vulnerability exists in AMD components in Apple macOS Mojave versions prior to 10.14.5
