The Code Signing feature in Apple OS X before 10.10 does not properly handle incomplete resource envelopes in signed bundles, which allows remote attackers to bypass intended app-author restrictions by omitting an execution-related resource.
La característica Firma de Código (Code Signing) en Apple OS X anterior a 10.10 no maneja debidamente los recursos incompletos en grupos firmados, lo que permite a atacantes remotos evadir las restricciones de app-author omitiendo un recurso relacionado con la ejecución.
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple OS X. 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 Gatekeeper. The issue lies in the usage of signed applications that do not sign the frameworks they depend on. An attacker can leverage this vulnerability to execute code under the context of the user.
