Category:	Red Hat Local Security Checks
Title:	RedHat Update for kernel RHSA-2016:2962-01
Summary:	The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'kernel' package(s) announced via the referenced advisory. Vulnerability Insight: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * A use-after-free vulnerability was found in the kernels socket recvmmsg subsystem. This may allows remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function. (CVE-2016-7117, Important) Bug Fix(es): * Previously, guest virtual machines (VMs) on a Hyper-V server cluster got in some cases rebooted during the graceful node failover test, because the host kept sending heartbeat packets independently of guests responding to them. This update fixes the bug by properly responding to all the heartbeat messages in the queue, even if they are pending. As a result, guest VMs no longer get rebooted under the described circumstances. (BZ#1391167) Affected Software/OS: kernel on Red Hat Enterprise Linux (v. 5 server) Solution: Please Install the Updated Packages. CVSS Score: 10.0 CVSS Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
