Re: [ADVISORY] Timing Attack on OpenSSL

This is a different vulnerability. The one you patched two weeks ago was caused by a failure to decrypt messages when the MAC comparison failed. This vulnerability is a timing attack against the RSA algorithms.

The Slashdot discussion is here:

The paper is here:
