Discussion

MIT Kerberos 5 KAdminD Server SVCAuth_GSS_Validate Stack Buffer Overflow Vulnerability

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 superuser privileges. A successful attack can result in the complete compromise of the application. Failed attempts will likely result in denial-of-service conditions.

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' 1.4 through 1.6.2 are vulnerable; third-party applications using the affected RPC library are also affected.
