Heimdal: Kerberos 4 buffer overflow in kadmin Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200405-23 (Heimdal: Kerberos 4 buffer overflow in kadmin) A buffer overflow was discovered in kadmind, a server for administrative access to the Kerberos database. Impact By sending a specially formatted message to kadmind, a remote attacker may be able to crash kadmind causing a denial of service, or execute arbitrary code with the permissions of the kadmind process. Workaround For a temporary workaround, providing you do not require Kerberos 4 support, you may turn off Kerberos 4 kadmin by running kadmind with the --no-kerberos4 option.
