https://notcve.org/view.php?id=CVE-2015-0837
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 •
CVE-2015-1606
https://notcve.org/view.php?id=CVE-2015-1606
The keyring DB in GnuPG before 2.1.2 does not properly handle invalid packets, which allows remote attackers to cause a denial of service (invalid read and use-after-free) via a crafted keyring file. La base de datos de llavero en GnuPG versiones anteriores a la versión 2.1.2, no maneja apropiadamente los paquetes no válidos, lo que permite a atacantes remotos causar una denegación de servicio (lectura no válida y uso de la memoria previamente liberada) por medio de un archivo de llavero especialmente diseñado. • http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git%3Ba=commit%3Bh=f0f71a721ccd7ab9e40b8b6b028b59632c0cc648 http://www.debian.org/security/2015/dsa-3184 http://www.openwall.com/lists/oss-security/2015/02/13/14 http://www.openwall.com/lists/oss-security/2015/02/14/6 http://www.securitytracker.com/id/1031876 https://blog.fuzzing-project.org/5-Multiple-issues-in-GnuPG-found-through-keyring-fuzzing-TFPA-0012015.html • CWE-416: Use After Free •
CVE-2014-9087
https://notcve.org/view.php?id=CVE-2014-9087
Integer underflow in the ksba_oid_to_str function in Libksba before 1.3.2, as used in GnuPG, allows remote attackers to cause a denial of service (crash) via a crafted OID in a (1) S/MIME message or (2) ECC based OpenPGP data, which triggers a buffer overflow. Desbordamiento de enteros en la función ksba_oid_to_str en Libksba anterior a 1.3.2, utilizado en GnuPG, permite a atacantes remotos causar una denegación de servicio (caída) a través de un OID manipulado en (1) un mensaje S/MIME o (2) datos OpenPGP basados en ECC, lo que provoca un desbordamiento de buffer. • http://advisories.mageia.org/MGASA-2014-0498.html http://lists.gnupg.org/pipermail/gnupg-announce/2014q4/000359.html http://secunia.com/advisories/60073 http://secunia.com/advisories/60189 http://secunia.com/advisories/60233 http://www.debian.org/security/2014/dsa-3078 http://www.mandriva.com/security/advisories?name=MDVSA-2014:234 http://www.mandriva.com/security/advisories?name=MDVSA-2015:151 http://www.securityfocus.com/bid/71285 http://www.ubuntu.com/usn/USN-2427-1 http • CWE-191: Integer Underflow (Wrap or Wraparound) •
CVE-2014-5270
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 •
CVE-2014-4617
https://notcve.org/view.php?id=CVE-2014-4617
The do_uncompress function in g10/compress.c in GnuPG 1.x before 1.4.17 and 2.x before 2.0.24 allows context-dependent attackers to cause a denial of service (infinite loop) via malformed compressed packets, as demonstrated by an a3 01 5b ff byte sequence. La función do_uncompress en g10/compress.c en GnuPG 1.x anterior a 1.4.17 y 2.x anterior a 2.0.24 permite a atacantes dependientes de contexto causar una denegación de servicio (bucle infinito) a través de paquetes comprimidos malformados, tal y como fue demostrado por una secuencia de bytes a3 01 5b ff. • http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git%3Ba=commit%3Bh=014b2103fcb12f261135e3954f26e9e07b39e342 http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git%3Ba=commit%3Bh=11fdfcf82bd8d2b5bc38292a29876e10770f4b0a http://lists.gnupg.org/pipermail/gnupg-announce/2014q2/000344.html http://lists.gnupg.org/pipermail/gnupg-announce/2014q2/000345.html http://lists.opensuse.org/opensuse-updates/2014-07/msg00010.html http://secunia.com/advisories/59213 http://secunia.com/advisories/59351 http://secunia.com/ad • CWE-20: Improper Input Validation •
