Описание
The build_principal_va function in lib/krb5/krb/bld_princ.c in MIT Kerberos 5 (aka krb5) before 1.14 allows remote authenticated users to cause a denial of service (out-of-bounds read and KDC crash) via an initial '\0' character in a long realm field within a TGS request.
An out-of-bounds flaw was discovered in MIT Kerberos; the build_principal_va() function did not properly duplicate the realm. An authenticated remote attacker could possibly exploit this flaw by sending a TGS request containing a specially crafted realm field and crashing the KDC (denial of service).
