CVE-2014-5270 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.53% chance of exploitation in the next 30 days.
