CVE-2013-6432
What it is
The ping_recvmsg function in net/ipv4/ping.c in the Linux kernel before 3.12.4 does not properly interact with read system calls on ping sockets, which allows local users to cause a denial of service (NULL pointer dereference and system crash) by leveraging unspecified privileges to execute a crafted application.
