Descriptions

Use-after-free vulnerability in the BitmapData class in the ActionScript 3 (AS3) implementation in Adobe Flash Player 13.x through 13.0.0.302 on Windows and OS X, 14.x through 18.0.0.203 on Windows and OS X, 11.x through 11.2.202.481 on Linux, and 12.x through 18.0.0.204 on Linux Chrome installations allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted Flash content that overrides a valueOf function, as exploited in the wild in July 2015.

Vulnerabilidad de uso después de liberación de memoria en la clase BitmapData en la implementación ActionScript 3 (AS3) en Adobe Flash Player 13.x hasta la versión 13.0.0.302 en Windows y OS X, 14.x hasta la versión 18.0.0.203 en Windows y OS X, 11.x hasta la versión 11.2.202.481 en Linux y 12.x hasta la versión 18.0.0.204 en instalaciones de Chrome de Linux permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de contenido Flash que anula una función valueOf, según se ha explotado activamente en julio de 2015.

The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash Player web browser plug-in. This update fixes two vulnerabilities in Adobe Flash Player. These vulnerabilities are detailed in the Adobe Security Bulletin APSB15-18 listed in the References section. Two flaws were found in the way flash-plugin displayed certain SWF content. An attacker could use these flaws to create a specially crafted SWF file that would cause flash-plugin to crash or, potentially, execute arbitrary code when the victim loaded a page containing the malicious SWF content.

Use-after-free vulnerability in the BitmapData class in the ActionScript 3 (AS3) implementation in Adobe Flash Player allows remote attackers to execute code or cause a denial-of-service (DoS).
