A specially crafted PDF document can trigger a previously freed object in memory to be reused, resulting in arbitrary code execution. An attacker needs to trick the user to open the malicious file to trigger this vulnerability. If the browser plugin extension is enabled, visiting a malicious site can also trigger the vulnerability."

Esta vulnerabilidad es diferente de CVE-2018-16292, CVE-2018-16293, CVE-2018-16294, CVE-2018-16295, CVE-2018-16296 y CVE-2018-16297. Un documento PDF especialmente manipulado puede hacer que se reutilice un objeto previamente liberado en la memoria, lo que resulta en la ejecución de código arbitrario. Un atacante necesita engañar a un usuario para que abra el archivo malicioso para desencadenar esta vulnerabilidad. Si la extensión del plugin del navegador está habilitada, visitar un sitio malicioso también puede desencadenar esta vulnerabilidad."
