CVE-2014-0100

Published: 11 March 2014

Race condition in the inet_frag_intern function in net/ipv4/inet_fragment.c in the Linux kernel through 3.13.6 allows remote attackers to cause a denial of service (use-after-free error) or possibly have unspecified other impact via a large series of fragmented ICMP Echo Request packets to a system with a heavy CPU load.

From the Ubuntu security team

Nikolay Aleksandrov discovered a race condition in Linux kernel's IPv4 fragment handling code. Remote attackers could exploit this flaw to cause a denial of service (system crash) or possibly have other unspecified impact.
