Descriptions

An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in macOS Mojave 10.14.4. An application may be able to read restricted memory.

Una lectura fuera de límites se abordó con una mejor comprobación de límites. Este problema es corregido en macOS Mojave versión 10.14.4. Una aplicación puede leer memoria restringida.

This vulnerability allows local attackers to disclose sensitive information 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 handling of the AMDRadeonX4000_AMDAccelResource method. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before reading from memory. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges in the context of the kernel.
