CVE-2012-0039
GLib Hash Collision DoS Vulnerability
Description

GLib 2.31.8 and earlier, when the g_str_hash function is used, computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this issue may be disputed by the vendor; the existence of the g_str_hash function is not a vulnerability in the library, because callers of g_hash_table_new and g_hash_table_new_full can specify an arbitrary hash function that is appropriate for the application.

    Removed Translation GLib v2.31.8 y anteriores, cuando se utiliza la funcion g_str_hash, calcula valores hash que podrían generar colisiones, permitiendo a atacantes dependientes de contexto causar una denegación de servicio (consumo de CPU) a través del envío de entradas (inputs) especialmente manipuladas a una aplicación que mantiene una tabla hash. NOTA: la existencia de la función g_str_hash no es una vulnerabilidad en la librería, llamadas de g_hash_table_new y g_hash_table_new_full puede especificar una función arbitraria hash que sea apropiada para la aplicación.
