Descriptions

Multiple memory corruption issues were addressed with improved input validation. This issue is fixed in macOS Sonoma 14.2. Processing a maliciously crafted file may lead to unexpected app termination or arbitrary code execution.

Se abordaron múltiples problemas de corrupción de memoria con una validación de entrada mejorada. Este problema se solucionó en macOS Sonoma 14.2. El procesamiento de un archivo creado con fines malintencionados puede provocar la finalización inesperada de la aplicación o la ejecución de código arbitrario.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Apple macOS. User interaction is required to exploit this vulnerability in that the target must receive a malicious image file that is written to the local filesystem.
The specific flaw exists within the processing of HEIC files in the VTDecoderXPCService process. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
