Descriptions

A memory corruption issue was addressed with improved input validation. This issue is fixed in macOS Big Sur 11.1, Security Update 2020-001 Catalina, Security Update 2020-007 Mojave. Processing a maliciously crafted image may lead to arbitrary code execution.

Se abordó un problema de corrupción de memoria con una comprobación mejorada de la entrada. Este problema es corregido en macOS Big Sur versión 11.1, Security Update 2020-001 Catalina, Security Update 2020-007 Mojave. El procesamiento de una imagen diseñada maliciosamente puede conllevar a una ejecución de código arbitraria.

This vulnerability allows remote attackers to disclose sensitive information on affected installations of Apple macOS. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the CoreGraphics framework. 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 buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
