A buffer overflow vulnerability was discovered in the SPNEGO implementation affecting the GSSAPI security policy negotiation in BIND, which could result in denial of service (daemon crash), or potentially the execution of arbitrary code (CVE-2020-8625). The default configuration is not vulnerable to this issue, but it is if the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options are set.
