Descriptions

The shmat system call in the System V Shared Memory interface for FreeBSD 5.2 and earlier, NetBSD 1.3 and earlier, and OpenBSD 2.6 and earlier, does not properly decrement a shared memory segment's reference count when the vm_map_find function fails, which could allow local users to gain read or write access to a portion of kernel memory and gain privileges.

La llamada de sistema shmat en el interfaz de Memoria Compartida de Sistema V de FreeBSD 5.2 y anteriores, NetBSD 1.3 y anteriores, y OpenBSD 2.6 y anteriores, no decrementa adecuadamente un contador de referencias de segmentos de memoria compartidos cuando al función vm_map_find falla, lo que podría permitir a usuarios locales ganar acceso de lectura y escritura a una porción de memoria del kernel y ganar privilegios.
