Zusammenfassung:	NOSUMMARY
Beschreibung:	Description: The remote host is missing updates announced in advisory RHSA-2012:1064. The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * 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) Red Hat would like to thank an anonymous contributor working with the Beyond Security SecuriTeam Secure Disclosure program for reporting CVE-2012-2744. Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date http://rhn.redhat.com/errata/RHSA-2012-1064.html Risk factor : High
