Red Hat Security Advisory 2014-0439-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A denial of service flaw was found in the way the Linux kernel's IPv6 implementation processed IPv6 router advertisement packets. An attacker able to send a large number of RA packets to a target system could potentially use this flaw to crash the target system. A flaw was found in the way the Linux kernel's netfilter connection tracking implementation for Datagram Congestion Control Protocol packets used the skb_header_pointer() function. A remote attacker could use this flaw to send a specially crafted DCCP packet to crash the system or, potentially, escalate their privileges on the system.
