Hi Team, k5_os_hostaddr() in krb5-1.16.1/src/lib/krb5/os/hostaddr.c calls getaddrinfo(name, 0, &hints, &ai) to get the addr info and store allocated memory to pointer "ai" later if fails to call malloc((i+1) * sizeof(*addrs)), function directly return without freeing the storage ai points to. The fix is to call "retval = ENOMEM; goto errout;" instead of "return ENOMEM;" Could someone help to take a look? Thanks, Bean
