-Subject: [PATCH] Fix KDC null deref on TGS inner body null server
-
-After the KDC decodes a FAST inner body, it does not check for a null
-server.  Prior to commit 39548a5b17bbda9eeb63625a201cfd19b9de1c5b this
-would typically result in an error from krb5_unparse_name(), but with
-the addition of get_local_tgt() it results in a null dereference.  Add
-a null check.
-
-Reported by Joseph Sutton of Catalyst.
-
-CVE-2021-37750:
-
-In MIT krb5 releases 1.14 and later, an authenticated attacker can
-cause a null dereference in the KDC by sending a FAST TGS request with
-no server field.
-
-ticket: 9008 (new)
-tags: pullup
-target_version: 1.19-next
-target_version: 1.18-next
