Descriptions

An exploitable out-of-bounds read vulnerability exists in the handling of certain XFA element attributes of Foxit Software's PDF Reader version 9.1.0.5096. A specially crafted PDF document can trigger an out-of-bounds read, which can disclose sensitive memory content and aid in exploitation when coupled with another vulnerability. 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.

Una vulnerabilidad de lectura fuera de límites explotable en la gestión de determinados atributos de elementos XFA de la versión 9.1.0.5096 del lector PDF de Foxit Software. Un documento PDF especialmente manipulado puede provocar una lectura fuera de límites, lo que puede divulgar contenido sensible de la memoria y servir de ayuda en tareas de explotación cuando va acompañado de otra vulnerabilidad. 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.
