Descriptions

An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in iOS 12.1.3, macOS Mojave 10.14.3, iTunes 12.9.3 for Windows. A malicious application may be able to elevate privileges.

Se abordó una lectura fuera de límites con la mejora de la comprobación de límites. Este problema se ha resuelto en iOS 12.1.3, macOS Mojave 10.14.3 y iTunes 12.9.3 para Windows. Una aplicación maliciosa podría ser capaz de escalar sus privilegios.

This vulnerability allows local attackers to escalate privileges on vulnerable installations of Apple iOS. 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 crte messages within the mediaserverd service. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root.
