Integer overflow in the ping_init_sock function in net/ipv4/ping.c in the
Linux kernel through 3.14.1 allows local users to cause a denial of service
(use-after-free and system crash) or possibly gain privileges via a crafted
application that leverages an improperly managed reference counter.

jdstrand | android kernels (goldfish, grouper, maguro, mako and manta) are not supported on the Ubuntu Touch 13.10 preview kernels |
tyhicks | android init writes a valid group range to /proc/sys/net/ipv4/ping_group_range which results in all unprivileged users being allowed to open restricted ICMP sockets and trigger this bug |
