CentOS Update for libvirt CESA-2011:0391 centos5 x86_64
Published: 2012-07-30 12:22:43
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:L/AC:M/Au:N/C:C/I:C/A:C
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 5
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 remotely managing virtualized systems.
It was found that several libvirt API calls did not honor the read-only
permission for connections. A local attacker able to establish a read-only
connection to libvirtd on a server could use this flaw to execute commands
that should be restricted to read-write connections, possibly leading to a
denial of service or privilege escalation. (CVE-2011-1146)
Note: Previously, using rpmbuild without the '--define 'rhel 5'' option to
build the libvirt source RPM on Red Hat Enterprise Linux 5 failed with a
'Failed build dependencies' error for the device-mapper-devel Linux Distribution Package, as
this -devel sub-Linux Distribution Package is not available on Red Hat Enterprise Linux 5.
With this update, the -devel sub-Linux Distribution Package is no longer checked by default as
a dependency when building on Red Hat Enterprise Linux 5, allowing the
libvirt source RPM to build as expected.
All libvirt users are advised to upgrade to these updated Linux Distribution Packages, which
contain a backported patch to resolve this issue. After installing the
updated Linux Distribution Packages, libvirtd must be restarted ('service libvirtd restart')
for this update to take effect.
Detection Type:
Linux Distribution Package
Solution Type:
Vendor Patch

What's vulnerability management?
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".
