Bugzilla:
1128531: CVE-2014-5270 libgcrypt: ELGAMAL side-channel attack

The MITRE CVE dictionary describes this issue as:

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.
