Descriptions
A memory corruption issue was addressed with improved input validation. This issue affected versions prior to macOS Mojave 10.14.
Un problema de corrupción de memoria se abordó con una validación de entradas mejorada. Este problema afectaba a macOS Mojave en versiones anteriores a la 10.14.
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 FODBWriteToAnnex method. The issue lies in the failure to properly validate the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current user.
macOS Mojave 10.14.1, Security Update 2018-001 High Sierra, and Security Update 2018-005 Sierra are now available and address buffer overflow, code execution, denial of service, and information leakage vulnerabilities.
