Descriptions

Use-after-free vulnerability in Adobe Digital Editions before 4.5.2 allows attackers to execute arbitrary code via unspecified vectors.

Vulnerabilidad de uso después de liberación de memoria en Adobe Digital Editions en versiones anteriores a 4.5.2 permite a atacantes ejecutar código arbitrario a través de vectores no especificados.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Digital Editions. 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.
