Descriptions

A use-after-free vulnerability exists in the way Foxit Reader 12.1.2.15332 handles destroying annotations. Specially crafted Javascript code inside a malicious PDF document can trigger reuse of a previously freed object, which can lead to memory corruption and result in arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

Existe una vulnerabilidad de uso después de la liberación en la forma en que Foxit Reader 12.1.2.15332 maneja la destrucción de anotaciones. El código Javascript especialmente manipulado dentro de un documento PDF malicioso puede desencadenar la reutilización de un objeto previamente liberado, lo que puede provocar daños en la memoria y provocar la ejecución de código arbitrario. Un atacante debe engañar al usuario para que abra el archivo malicioso para desencadenar esta vulnerabilidad. La explotación también es posible si un usuario visita un sitio malicioso especialmente manipulado si la extensión del complemento del navegador está habilitada.
