Descriptions

A memory corruption issue was addressed with improved input validation. This issue is fixed in macOS Catalina 10.15.6. Viewing a maliciously crafted JPEG file may lead to arbitrary code execution.

Se abordó un problema de corrupción de la memoria con una comprobación de entrada mejorada. Este problema es corregido en macOS Catalina versión 10.15.6. Al visualizar un archivo JPEG diseñado maliciosamente puede conllevar a una ejecución de código arbitraria

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Apple macOS. Interaction with the ImageIO library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.
The specific flaw exists within the AppleVPA framework. Crafted data in a JPEG image can trigger a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process.
