Descriptions

Adobe Flash Player before 18.0.0.232 on Windows and OS X and before 11.2.202.508 on Linux, Adobe AIR before 18.0.0.199, Adobe AIR SDK before 18.0.0.199, and Adobe AIR SDK & Compiler before 18.0.0.199 allow attackers to execute arbitrary code by leveraging an unspecified "type confusion," a different vulnerability than CVE-2015-5554, CVE-2015-5555, and CVE-2015-5562.

Vulnerabilidad en Adobe Flash Player en versiones anteriores a 18.0.0.232 en Windows y OS X y versiones anteriores a 11.2.202.508 en Linux, en Adobe AIR en versiones anteriores a 18.0.0.199, Adobe AIR SDK en versiones anteriores a 18.0.0.199 y Adobe AIR SDK & Compiler en versiones anteriores a 18.0.0.199, permite a atacantes ejecutar código arbitrario mediante el aprovechamiento de un ataque 'type confusion' no especificado, una vulnerabilidad diferente a CVE-2015-5554, CVE-2015-5555 y CVE-2015-5562.

There is a type confusion issue in the TextFormat constructor that is reachable because the FileReference constructor does not verify that the incoming object is of type Object (it only checks that the object is not native backed). The TextFormat constructor first sets a new object to type TextFormat, and then calls into script several times before setting the native backing object. If one of these script calls then calls into the FileReference constructor, the object can be set to type FileReference, and then the native object will be set to the TextFormat, leading to type confusion.
