CentOS Update for libvirt CESA-2012:1202 centos6

Published: 2012-08-24 04:25:57
CVE Author: NIST National Vulnerability Database

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

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

Affected Versions:
libvirt on CentOS 6

Recommendations:
Please install the updated Linux Distribution Packages.

Technical Details:
The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. A flaw was found in libvirtd's RPC call handling. An attacker able to establish a read-only connection to libvirtd could trigger this flaw with a specially-crafted RPC command that has the number of parameters set to 0, causing libvirtd to access invalid memory and crash. (CVE-2012-3445) This update also fixes the following bugs: * Previously, repeatedly migrating a guest between two machines while using the tunnelled migration could cause the libvirt daemon to lock up unexpectedly. The bug in the code for locking remote drivers has been fixed and repeated tunnelled migrations of domains now work as expected. (BZ#847946) * Previously, when certain system locales were used by the system, libvirt could issue incorrect commands to the hypervisor. This bug has been fixed and the libvirt library and daemon are no longer affected by the choice of the user locale. (BZ#847959) All users of libvirt are advised to upgrade to these updated Linux Distribution Packages, which contain backported patches to correct these issues. After installing the updated Linux Distribution Packages, libvirtd will be restarted automatically.

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".
