critical Nessus Plugin ID 26006
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Mandrake Linux host is missing one or more security updates.

Description

A stack-based buffer overflow vulnerability was discovered in the RPC library used by Kerberos' kadmind program by Tenable Network Security.
A remote unauthenticated user who could access kadmind would be able to trigger the flaw and cause it to crash (CVE-2007-3999). This issue is only applicable to Kerberos 1.4 and higher.

Garrett Wollman found an uninitialized pointer vulnerability in kadmind which a remote unauthenticated attacker able to access kadmind could exploit to cause kadmind to crash (CVE-2007-4000). This issue is only applicable to Kerberos 1.5 and higher.

Update :

The MIT Kerberos Team found a problem with the originally published patch for CVE-2007-3999. A remote unauthenticated attacker able to access kadmind could trigger this flaw and cause kadmind to crash.

Updated packages have been patched to prevent these issues.

Solution

Update the affected packages.
