Technical Details:
Tavis Ormandy discovered a heap overflow flaw during video-to-video copy operations in the Cirrus VGA extension code that is used in Xen. A malicious local administrator of a guest domain could potentially trigger this flaw and execute arbitrary code outside of the domain (CVE-2007-1320). Tavis Ormandy also discovered insufficient input validation leading to a heap overflow in the NE2000 network driver in Xen. If the driver is in use, a malicious local administrator of a guest domain could potentially trigger this flaw and execute arbitrary code outside of the domain (CVE-2007-1321, CVE-2007-5729, CVE-2007-5730). Steve Kemp found that xen-utils used insecure temporary files within the xenmon tool that could allow local users to truncate arbitrary files (CVE-2007-3919). Joris van Rantwijk discovered a flaw in Pygrub, which is used as a boot loader for guest domains. A malicious local administrator of a guest domain could create a carefully-crafted grub.conf file which could trigger the execution of arbitrary code outside of that domain (CVE-2007-4993). Updated Linux Distribution Packages have been patched to prevent these issues.

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".
