Descriptions

Use-after-free vulnerability in Foxit Reader and PhantomPDF before 7.3.4 on Windows allows remote attackers to execute arbitrary code via a crafted FlateDecode stream in a PDF document.

Vulnerabilidad de uso después de liberación de memoria en Foxit Reader y PhantomPDF en versiones anteriores a 7.3.4 en Windows permite a atacantes remotos ejecutar código arbitrario a través de un flujo FlateDecode modificado en un documento PDF.

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 FlateDecode. A specially crafted PDF with a specific FlateDecode stream can force a dangling pointer to be reused after it has been freed. An attacker could leverage this vulnerability to execute arbitrary code under the context of the current process.
