CVE Author: NIST National Vulnerability Database

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

Summary:
Check for the Version of krb5-devel

Affected Versions:
krb5-devel on CentOS 4

Recommendations:
Please Install the Updated Packages.

Technical Details:
Kerberos is a network authentication system which allows clients and servers to authenticate to each other through use of symmetric encryption and a trusted third party, the KDC. A flaw was found in the way the MIT Kerberos Authentication Service and Key Distribution Center server (krb5kdc) handled Kerberos v4 protocol packets. An unauthenticated remote attacker could use this flaw to crash the krb5kdc daemon, disclose portions of its memory, or possibly execute arbitrary code using malformed or truncated Kerberos v4 protocol requests. (CVE-2008-0062, CVE-2008-0063) This issue only affected krb5kdc with Kerberos v4 protocol compatibility enabled, which is the default setting on Red Hat Enterprise Linux 4. Kerberos v4 protocol support can be disabled by adding " v4_mode=none" (without the quotes) to the " [kdcdefaults]" section of /var/kerberos/krb5kdc/kdc.conf. Red Hat would like to thank MIT for reporting these issues. A double-free flaw was discovered in the GSSAPI library used by MIT Kerberos. This flaw could possibly cause a crash of the application using the GSSAPI library. (CVE-2007-5971) All krb5 users are advised to update to these erratum Linux Distribution Packages which contain backported fixes to correct 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".
