RPC: MIT Kerberos Kadmind Lib Overflow

This signature detects attempts to exploit a known vulnerability in the MIT Kerberos Kadmind. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the deamon.

Extended Description

Kerberos 5 'kadmind' (Kerberos Administration Daemon) server is prone to a stack-based buffer-overflow vulnerability because the software fails to adequately bounds-check user-supplied data before copying it to an insufficiently sized buffer. An attacker can exploit this issue to execute arbitrary code with administrative privileges. A successful attack can result in the complete compromise of the application. Failed attempts will likely result in denial-of-service conditions. This issue also affects third-party applications using the affected RPC library. All 'kadmind' servers run on the master Kerberos server. Since the master server holds the KDC principal and policy database, an attack may not only compromise the affected computer, but could also compromise multiple hosts that use the server for authentication. Kerberos 5 'kadmind' 1.6.1 and prior versions are vulnerable.
