Descriptions

Use-after-free vulnerability in the XFA forms handling functionality in Foxit Reader and PhantomPDF before 7.3.4 on Windows allows remote attackers to execute arbitrary code via a crafted remerge call.

Vulnerabilidad de uso después de liberación de memoria en la funcionalidad de manejo de formularios XFA en Foxit Reader y PhantomPDF en versiones anteriores a 7.3.4 en Windows permite a atacantes remotos ejecutar código arbitrario a través de una llamada remerge manipulada.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Foxit Reader. 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 the handling of XFA forms. A specially crafted remerge call can force a dangling pointer to be reused after it has been freed. An attacker can leverage this vulnerability to execute code under the context of the current process.
