Package(s):kernel CVE #(s):CVE-2012-2744 CVE-2012-2745
Created:July 10, 2012 Updated:October 24, 2012
Description: From the Red Hat advisory:

* A NULL pointer dereference flaw was found in the nf_ct_frag6_reasm() function in the Linux kernel's netfilter IPv6 connection tracking implementation. A remote attacker could use this flaw to send specially-crafted packets to a target system that is using IPv6 and also has the nf_conntrack_ipv6 kernel module loaded, causing it to crash. (CVE-2012-2744, Important)

* A flaw was found in the way the Linux kernel's key management facility handled replacement session keyrings on process forks. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2745, Moderate)
