Descriptions

The signatureSetSeedValue method in Adobe Reader and Acrobat 10.x before 10.1.16 and 11.x before 11.0.13, Acrobat and Acrobat Reader DC Classic before 2015.006.30094, and Acrobat and Acrobat Reader DC Continuous before 2015.009.20069 on Windows and OS X allows attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted arguments, a different vulnerability than CVE-2015-6685, CVE-2015-6686, CVE-2015-6694, CVE-2015-6695, and CVE-2015-7622.

El método signatureSetSeedValue en Adobe Reader y Acrobat 10.x en versiones anteriores a 10.1.16 y 11.x en versiones anteriores a 11.0.13, Acrobat y Acrobat Reader DC Classic en versiones anteriores a 2015.006.30094 y Acrobat y Acrobat Reader DC Continuous en versiones anteriores a 2015.009.20069 en Windows y OS X permite a atacantes ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria) a través de argumentos manipulados, una vulnerabilidad diferente a CVE-2015-6685, CVE-2015-6686, CVE-2015-6694, CVE-2015-6695 y CVE-2015-7622.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Acrobat DC. 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 signatureSetSeedValue method. Specially crafted arguments passed to signatureSetSeedValue can force a dangling pointer to be reused after it has been freed. An attacker can leverage this vulnerability to execute arbitrary code under the context of the current process.
