Hi Team, In krb5-1.16.1/src/lib/krb5/os/hostrealm_domain.c, domain_fallback_realm() assigns the storage returned from strdup() to uhost, but later if calling profile_get_integer() fails, this function returns without freeing the storage uhost points to. The fix is simple, just call "goto cleanup" instead of "return ret" if calling profile_get_integer() fails. Could someone help to take a look? Thanks, Bean
