In a configuration which uses BIND\u0027s default settings the vulnerable code path is not exposed, but a server can be rendered vulnerable by explicitly setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options. Although the default configuration is not vulnerable, GSS-TSIG is frequently used in networks where BIND is integrated with Samba, as well as in mixed-server environments that combine BIND servers with Active Directory domain controllers. The most likely outcome of a successful exploitation of the vulnerability is a crash of the named process. However, remote code execution, while unproven, is theoretically possible. Affects: BIND 9.5.0 -\u003e 9.11.27, 9.12.0 -\u003e 9.16.11, and versions BIND 9.11.3-S1 -\u003e 9.11.27-S1 and 9.16.8-S1 -\u003e 9.16.11-S1 of BIND Supported Preview Edition.
