Description Agostino Sarubbo gentoo-dev 2014-04-26 14:32:49 UTC 
CVE-2014-2851 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-2851):

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.
