Fix a side-channel attack which can potentially lead to an information leak. (CVE-2014-3591)
Libgcrypt before 1.5.4, as used in GnuPG and other products, does not properly perform ciphertext normalization and ciphertext randomization, which makes it easier for physically proximate attackers to conduct key-extraction attacks by leveraging the ability to collect voltage data from exposed metal, a different vector than CVE-2013-4576, which was fixed in <a href="https://alas.aws.amazon.com/ALAS-2014-278.html">ALAS-2014-278</a>.
