DESCRIPTION:
Some weaknesses have been reported in the Linux Kernel, which can be
exploited by malicious, local users to disclose certain system
information.
1) The "l2cap_sock_getsockopt_old()" function in
net/bluetooth/l2cap_sock.c does not properly initialise a structure
before copying it to userspace, which can be exploited to disclose
kernel stack memory.
2) The "rfcomm_sock_getsockopt_old()" function in
net/bluetooth/rfcomm/sock.c does not properly initialise a structure
before copying it to userspace, which can be exploited to disclose
kernel stack memory.
SOLUTION:
Restrict access to trusted users only.
