The ping_unhash function in net/ipv4/ping.c in the Linux kernel before
4.0.3 does not initialize a certain list data structure during an unhash
operation, which allows local users to gain privileges or cause a denial of
service (use-after-free and system crash) by leveraging the ability to make
a SOCK_DGRAM socket system call for the IPPROTO_ICMP or IPPROTO_ICMPV6
protocol, and then making a connect system call after a disconnect.
