CVE-2015-8080

Desbordamiento de entero en la función getnum en lua_struct.c en Redis 2.8.x en versiones anteriores a 2.8.24 y 3.0.x en versiones anteriores a 3.0.6 permite a atacantes dependientes de contexto con permiso para ejecutar código Lua en una sesión Redis provocar una denegación de servicio (corrupción de memoria y caída de la aplicación) o posiblemente eludir restricciones destinadas a la sandbox a través de un número grande, lo que desencadena un desbordamiento de buffer basado en pila.

An integer-wraparound flaw leading to a stack-based overflow was found in Redis. A user with access to run Lua code in a Redis session could possibly use this flaw to crash the server (denial of service) or gain code execution outside of the Lua sandbox.

Redis is an advanced key-value store. It is often referred to as a data structure server because keys can contain strings, hashes, lists, sets, or sorted sets. An integer-wraparound flaw leading to a stack-based overflow was found in Redis. A user with access to run Lua code in a Redis session could possibly use this flaw to crash the server or gain code execution outside of the Lua sandbox. All users of redis are advised to upgrade to these updated packages, which correct this issue.
