CVE-2014-0100

Status Candidate

Overview

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.

Red Hat Security Advisory 2014-0557-01
Posted May 28, 2014

Red Hat Security Advisory 2014-0557-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A race condition leading to a use-after-free flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled the addition of fragments to the LRU list under certain conditions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system by sending a large amount of specially crafted fragmented packets to that system.
