CentOS Update for kernel CESA-2014:0328 centos6

Published: 2014-04-03 05:55:22
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:N/C:N/I:N/A:C

Affected Versions:
kernel on CentOS 6

Technical Details:
The kernel Linux Distribution Packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the get_rx_bufs() function in the vhost_net implementation in the Linux kernel handled error conditions reported by the vhost_get_vq_desc() function. A privileged guest user could use this flaw to crash the host. (CVE-2014-0055, Important) * A flaw was found in the way the Linux kernel processed an authenticated COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote attacker could use this flaw to crash the system by initiating a specially crafted SCTP handshake in order to trigger a NULL pointer dereference on the system. (CVE-2014-0101, Important) * A flaw was found in the way the Linux kernel's CIFS implementation handled uncached write operations with specially crafted iovec structures. An unprivileged local user with access to a CIFS share could use this flaw to crash the system, leak kernel memory, or, potentially, escalate their privileges on the system. Note: the default cache settings for CIFS mounts on Red Hat Enterprise Linux 6 prohibit a successful exploitation of this issue. (CVE-2014-0069, Moderate) * A heap-based buffer overflow flaw was found in the Linux kernel's cdc-wdm driver, used for USB CDC WCM device management. An attacker with physical access to a system could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1860, Low) Red Hat would like to thank Nokia Siemens Networks for reporting CVE-2014-0101, and Al Viro for reporting CVE-2014-0069. 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 Linux Distribution Packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

Recommendations:
Please install the updated Linux Distribution Packages.

Detection Type:
Linux Distribution Package

Solution Type:
Vendor Patch

Summary:
The remote host is missing an update for the 'kernel' Linux Distribution Package(s) announced via the referenced advisory.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
