Descriptions
The bluetooth subsystem in the Linux kernel before 3.0-rc4 does not properly initialize certain data structures, which allows local users to obtain potentially sensitive information from kernel memory via a crafted getsockopt system call, related to (1) the l2cap_sock_getsockopt_old function in net/bluetooth/l2cap_sock.c and (2) the rfcomm_sock_getsockopt_old function in net/bluetooth/rfcomm/sock.c.
El subsistema de bluetooth en el kernel de Linux anteriores a v3.0-rc4 no inicializa correctamente algunas estructuras de datos, lo que permite a usuarios locales obtener información sensible de la memoria del kernel a través de una llamada getsockopt manipulada, en relación con (1) la función l2cap_sock_getsockopt_old en net/bluetooth/l2cap_sock.c y (2) la función rfcomm_sock_getsockopt_old en net/bluetooth/rfcomm/sock.c.
