CentOS Update for kernel CESA-2012:1304 centos6

Published: 2012-09-27 03:37:08
CVE Author: NIST National Vulnerability Database

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

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

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: * An integer overflow flaw was found in the i915_gem_do_execbuffer() function in the Intel i915 driver in the Linux kernel. A local, unprivileged user could use this flaw to cause a denial of service. This issue only affected 32-bit systems. (CVE-2012-2384, Moderate) * A memory leak flaw was found in the way the Linux kernel's memory subsystem handled resource clean up in the mmap() failure path when the MAP_HUGETLB flag was set. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2390, Moderate) * A race condition was found in the way access to inet->opt ip_options was synchronized in the Linux kernel's TCP/IP protocol suite implementation. Depending on the network facing applications running on the system, a remote attacker could possibly trigger this flaw to cause a denial of service. A local, unprivileged user could use this flaw to cause a denial of service regardless of the applications the system runs. (CVE-2012-3552, Moderate) * A flaw was found in the way the Linux kernel's dl2k driver, used by certain D-Link Gigabit Ethernet adapters, restricted IOCTLs. A local, unprivileged user could use this flaw to issue potentially harmful IOCTLs, which could cause Ethernet adapters using the dl2k driver to malfunction (for example, losing network connectivity). (CVE-2012-2313, Low) * A flaw was found in the way the msg_namelen variable in the rds_recvmsg() function of the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation was initialized. A local, unprivileged user could use this flaw to leak kernel stack memory to user-space. (CVE-2012-3430, Low) Red Hat would like to thank Hafid Lin for reporting CVE-2012-3552, and Stephan Mueller for reporting CVE-2012-2313. The CVE-2012-3430 issue was discovered by the Red Hat InfiniBand team. 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, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect.

Detection Type:

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".
