libgcrypt: ELGAMAL side-channel attack

Published Oct 10, 2014 CVSS 2.0 · 2.1 Low EPSS < 1% KEV · Not listed
Description
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.
