After a standard system update you need to reboot your computer to make all the necessary changes.

Details follow:

Nelson Elhage discovered several problems with the Acorn Econet protocol driver. A local user could cause a denial of service via a NULL pointer dereference, escalate privileges by overflowing the kernel stack, and assign Econet addresses to arbitrary interfaces.

Linux Kernel contains a flaw related to the the 'ec_dev_ioctl' function in 'net/econet/af_econet.c'. The issue is triggered when a local attacker uses a SIOCSIFADDR iotcl call to bypass access restrictions and configure econet addresses.

Linux Kernel contains a flaw that may allow a local denial of service. The issue is triggered when the 'econet_sendmsg' function in 'net/econet/af_econet.c' alows local users to use a sendmsg call which specifies a NULL value for the remote address field to cause a denial of service via a NULL pointer dereference.
70260 Linux Kernel net/econet/af_econet.c econet_sendmsg Function iovec Structure L...

Linux Kernel is prone to an overflow condition. The 'econet_sendmsg' function in 'net/econet/af_econet.c' fails to properly sanitize user-supplied input resulting in a stack-based buffer overflow. By providing a large number of iovec structures, a local attacker can gain elevated privileges.
