The mpi_powm function in Libgcrypt before 1.6.3 and GnuPG before 1.4.19 allows attackers to obtain sensitive information by leveraging timing differences when accessing a pre-computed table during modular exponentiation, related to a "Last-Level Cache Side-Channel Attack." La función mpi_powm en Libgcrypt versiones anteriores a 1.6.3 y GnuPG versiones anteriores a 1.4.19, permite a atacantes obtener información confidencial mediante el aprovechamiento de las diferencias de tiempo al acceder a una tabla precalculada durante una exponenciación modular, relacionada con un "Last-Level Cache Side-Channel Attack". • http://www.debian.org/security/2015/dsa-3184 http://www.debian.org/security/2015/dsa-3185 https://ieeexplore.ieee.org/document/7163050 https://lists.gnupg.org/pipermail/gnupg-announce/2015q1/000363.html https://lists.gnupg.org/pipermail/gnupg-announce/2015q1/000364.html • CWE-203: Observable Discrepancy •

https://notcve.org/view.php?id=CVE-2014-5270
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. • http://lists.gnupg.org/pipermail/gnupg-announce/2014q3/000352.html http://openwall.com/lists/oss-security/2014/08/16/2 http://www.cs.tau.ac.il/~tromer/handsoff http://www.debian.org/security/2014/dsa-3024 http://www.debian.org/security/2014/dsa-3073 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 1.9EPSS: 0%CPEs: 96EXPL: 0CVE-2013-4242 – GnuPG susceptible to Yarom/Falkner flush+reload cache side-channel attack
https://notcve.org/view.php?id=CVE-2013-4242
GnuPG before 1.4.14, and Libgcrypt before 1.5.3 as used in GnuPG 2.0.x and possibly other products, allows local users to obtain private RSA keys via a cache side-channel attack involving the L3 cache, aka Flush+Reload. GnuPG anterior a 1.4.14, y Libgcrypt anterior a 1.5.3 usado en GnuPG 2.0.x y posiblemente otros productos, permite a usuarios locales obtener las claves RSA privadas a través de un ataque "side-channel" que involucra la caché L3. Aka Flush+Reload. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717880 http://eprint.iacr.org/2013/448 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://lists.gnupg.org/pipermail/gnupg-announce/2013q3/000330.html http://lists.opensuse.org/opensuse-updates/2013-08/msg00003.html http://rhn.redhat.com/errata/RHSA-2013-1457.html http://secunia.com/advisories/54318 http://secunia.com/advisories/54321 http://secunia.com/advisories/54332 http://secunia.com/advisories/54375 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
