CentOS Update for kernel CESA-2013:1051 centos6

Published: 2013-08-01 13:13:39
CVE Author: NIST National Vulnerability Database

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

Affected Versions:
kernel on CentOS 6

Recommendations:
Please install the updated Linux Distribution Packages.

Technical Details:
The kernel Linux Distribution Packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues: * A flaw was found in the tcp_read_sock() function in the Linux kernel's IPv4 TCP/IP protocol suite implementation in the way socket buffers (skb) were handled. A local, unprivileged user could trigger this issue via a call to splice(), leading to a denial of service. (CVE-2013-2128, Moderate) * Information leak flaws in the Linux kernel could allow a local, unprivileged user to leak kernel memory to user-space. (CVE-2012-6548, CVE-2013-2634, CVE-2013-2635, CVE-2013-3222, CVE-2013-3224, CVE-2013-3225, Low) * An information leak was found in the Linux kernel's POSIX signals implementation. A local, unprivileged user could use this flaw to bypass the Address Space Layout Randomization (ASLR) security feature. (CVE-2013-0914, Low) * A format string flaw was found in the ext3_msg() function in the Linux kernel's ext3 file system implementation. A local user who is able to mount an ext3 file system could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1848, Low) * A format string flaw was found in the b43_do_request_fw() function in the Linux kernel's b43 driver implementation. A local user who is able to specify the 'fwpostfix' b43 module parameter could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-2852, Low) * A NULL pointer dereference flaw was found in the Linux kernel's ftrace and function tracer implementations. A local user who has the CAP_SYS_ADMIN capability could use this flaw to cause a denial of service. (CVE-2013-3301, Low) Red Hat would like to thank Kees Cook for reporting CVE-2013-2852. 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. Users should 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.

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".
