Descriptions

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.

Libgcrypt anterior a 1.5.4, utilizado en GnuPG y otros productos, no realiza debidamente la normalización y aleatorización de texto cifrado, lo que facilita a atacantes físicamente próximos realizar ataques de extracción de claves mediante el aprovechamiento de la habilidad de recoger datos de voltaje del metal expuesto, un vector deferente a CVE-2013-4576.
