Description

The remote host is affected by the vulnerability described in GLSA-200701-21 (MIT Kerberos 5: Arbitrary Remote Code Execution)

The Kerberos administration daemon, and possibly other applications using the GSS-API or RPC libraries, could potentially call a function pointer in a freed heap buffer, or attempt to free an uninitialized pointer.
