Descriptions

A use-after-free vulnerability was discovered in Adobe Flash Player before 28.0.0.161. This vulnerability occurs due to a dangling pointer in the Primetime SDK related to media player handling of listener objects. A successful attack can lead to arbitrary code execution. This was exploited in the wild in January and February 2018.

Se ha descubierto una vulnerabilidad de uso de memoria previamente liberada en Adobe Flash Player, en versiones anteriores a la 28.0.0.161. Esta vulnerabilidad ocurre debido a un puntero pendiente en el SDK Primetime relacionado con la gestión de objetos listener del media player. Un ataque con éxito podría permitir la ejecución arbitraria de código. Esto fue explotado "in the wild" en enero y febrero de 2018.

The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash Player web browser plug-in. This update upgrades Flash Player to version 28.0.0.161. Security Fix: This update fixes multiple vulnerabilities in Adobe Flash Player. These vulnerabilities, detailed in the Adobe Security Bulletin listed in the References section, could allow an attacker to create a specially crafted SWF file that would cause flash-plugin to crash, execute arbitrary code, or disclose sensitive information when the victim loaded a page containing the malicious SWF content.

Adobe Flash Player contains a use-after-free vulnerability that could allow for code execution.
