I'm glad to share this to you guys. The test code was attached. You
|
|
also could find them here:

CVE-2013-1663[1] is a possible remote DOS attack issue. This issue has
|
|
been fixed[2] in >=GNUTLS-3.0.14. I hacked on it for hours and figure out
|
|
a few prerequisites could make it vulnerable:
|
|
|
|
=============================
|
|
REQUIRED:
|
|
|
|
- prior to GNUTLS 3.0.14
|
|
- crafted certificate
|
|
|
|
=============================
|
|
Attacking SCENES
|
|
|
|
- a client import a crafted cert file for sending req to server( CA?)
|
|
|
|
- a "server" import a crafted cert file for sending req to other
|
|
server( CA?)
|
|
|
|
---> With high frequency uses above manipulations
|
|
|
|
Stand on the client side, the attacker should try to construct a
|
|
crafted certificate for triggering the below function fails:
|
|
|
|
ret = gnutls_pubkey_import_x509(pcert->pubkey, crt, 0);
|
|
if (ret < 0)
|
|
{
|
|
gnutls_pubkey_deinit(pcert->pubkey);
|
|
/* pcert->pubkey should be NULL now */
|
|
ret = gnutls_assert_val(ret);
|
|
goto cleanup;
|
|
}
|
|
|
|
I made up two crafted cert files( client.pem, client2.pem) seems would
|
|
trigger the double free issue in client's side.
|
|
|
|
Warning: Don't try it on your host machine because it would cost too
|
|
much memory then makes your machine very slow.
