ID de Prueba:	1.3.6.1.4.1.25623.1.0.871165
Categoría:	Red Hat Local Security Checks
Título:	RedHat Update for kernel RHSA-2014:0475-01
Resumen:	The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Descripción:	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. * A flaw was found in the way the Linux kernel's netfilter connection tracking implementation for Datagram Congestion Control Protocol (DCCP) 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. (CVE-2014-2523, Important) * A flaw was found in the way the Linux kernel's Adaptec RAID controller (aacraid) checked permissions of compat IOCTLs. A local attacker could use this flaw to bypass intended security restrictions. (CVE-2013-6383, Moderate) * A flaw was found in the way the handle_rx() function handled large network packets when mergeable buffers were disabled. A privileged guest user could use this flaw to crash the host or corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process. (CVE-2014-0077, Moderate) The CVE-2014-0077 issue was discovered by Michael S. Tsirkin of Red Hat. This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect. Affected Software/OS: kernel on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6), Red Hat Enterprise Linux Workstation (v. 6) Solution: Please Install the Updated Packages. CVSS Score: 10.0 CVSS Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
