CVE-2014-5270 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:14.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream gnupg package and not the gnupg package as distributed by Ubuntu.
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.
