Descriptions

Use-after-free vulnerability in Adobe Flash Player before 18.0.0.366 and 19.x through 22.x before 22.0.0.209 on Windows and OS X and before 11.2.202.632 on Linux allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2016-4173, CVE-2016-4222, CVE-2016-4226, CVE-2016-4227, CVE-2016-4228, CVE-2016-4229, CVE-2016-4230, CVE-2016-4231, and CVE-2016-4248.

Uso después de liberación de memoria en Adobe Flash Player en versiones anteriores a 18.0.0.366 y 19.x hasta la versión 22.x en versiones anteriores a 22.0.0.209 en Windows y OS X y en versiones anteriores a 11.2.202.632 en Linux permite a atacantes ejecutar código arbitrario a través de vectores no especificados, una vulnerabilidad diferente a CVE-2016-4173, CVE-2016-4222, CVE-2016-4226, CVE-2016-4227, CVE-2016-4228, CVE-2016-4229, CVE-2016-4230, CVE-2016-4231 y CVE-2016-4248.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Flash. 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 StyleSheet objects. By calling the parseCSS method of the StyleSheet object from within a specific callback function, an attacker 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.
