-Subject: Fix build_principal memory bug [CVE-2015-2697]
-
-In build_principal_va(), use k5memdup0() instead of strdup() to make a
-copy of the realm, to ensure that we allocate the correct number of
-bytes and do not read past the end of the input string.  This bug
-affects krb5_build_principal(), krb5_build_principal_va(), and
-krb5_build_principal_alloc_va().  krb5_build_principal_ext() is not
-affected.

-CVE-2015-2697:
-
-In MIT krb5 1.7 and later, an authenticated attacker may be able to
-cause a KDC to crash using a TGS request with a large realm field
-beginning with a null byte.  If the KDC attempts to find a referral to
-answer the request, it constructs a principal name for lookup using
-krb5_build_principal() with the requested realm.  Due to a bug in this
-function, the null byte causes only one byte be allocated for the
-realm field of the constructed principal, far less than its length.
-Subsequent operations on the lookup principal may cause a read beyond
-the end of the mapped memory region, causing the KDC process to crash.
