Published: 2012-08-03 05:47:01
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:A/AC:L/Au:S/C:N/I:N/A:P
Summary:
The remote host is missing an update for the 'xen'
Linux Distribution Package(s) announced via the referenced advisory.
Affected Versions:
xen on CentOS 5
Recommendations:
Please install the updated Linux Distribution Packages.
Technical Details:
The xen Linux Distribution Packages contain administration tools and the xend service for
managing the kernel-xen kernel for virtualization on Red Hat Enterprise
Linux.
A flaw was found in the way the pyGrub boot loader handled compressed
kernel images. A privileged guest user in a para-virtualized guest (a DomU)
could use this flaw to create a crafted kernel image that, when attempting
to boot it, could result in an out-of-memory condition in the privileged
domain (the Dom0). (CVE-2012-2625)
Red Hat would like to thank Xinli Niu for reporting this issue.
All users of xen are advised to upgrade to these updated Linux Distribution Packages, which
contain a backported patch to correct this issue. After installing the
updated Linux Distribution Packages, the xend service must be restarted 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".
