Descriptions

An issue was discovered in Adobe Flash Player 27.0.0.183 and earlier versions. This vulnerability occurs as a result of a computation that reads data that is past the end of the target buffer; the computation is part of providing language- and region- or country- specific functionality. The use of an invalid (out-of-range) pointer offset during access of internal data structure fields causes the vulnerability. A successful attack can lead to sensitive data exposure.

Se ha descubierto un problema en Adobe Flash Player 27.0.0.183 y anteriores. La vulnerabilidad ocurre como resultado de un cálculo que lee datos más allá del búfer objetivo; el cálculo forma parte de la funcionalidad específica de idioma, región o país. El uso de un puntero inválido (fuera de rango) durante el acceso a los campos de la estructura de datos interna provoca esta vulnerabilidad. Un ataque con éxito podría conducir a la exposición de datos sensibles.

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 handling of LocaleID's determinePreferredLocales method. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this vulnerability to execute code under the context of current process.
