https://notcve.org/view.php?id=CVE-2015-1607
kbx/keybox-search.c in GnuPG before 1.4.19, 2.0.x before 2.0.27, and 2.1.x before 2.1.2 does not properly handle bitwise left-shifts, which allows remote attackers to cause a denial of service (invalid read operation) via a crafted keyring file, related to sign extensions and "memcpy with overlapping ranges." El archivo kbx/keybox-search.c en GnuPG versiones anteriores a 1.4.19, versiones 2.0.x anteriores a 2.0.27 y versiones 2.1.x anteriores a 2.1.2, no maneja apropiadamente los cambios a la izquierda bit a bit, lo que permite a atacantes remotos causar una denegación de servicio (operación de lectura no válida) por medio de un archivo de llavero diseñado, relacionado con extensiones de signo y "memcpy with overlapping ranges." • http://git.gnupg.org/cgi-bin/gitweb.cgi?p=gnupg.git%3Ba=commit%3Bh=2183683bd633818dd031b090b5530951de76f392 http://www.openwall.com/lists/oss-security/2015/02/13/14 http://www.openwall.com/lists/oss-security/2015/02/14/6 http://www.securityfocus.com/bid/72610 http://www.ubuntu.com/usn/usn-2554-1 https://blog.fuzzing-project.org/5-Multiple-issues-in-GnuPG-found-through-keyring-fuzzing-TFPA-0012015.html https://lists.gnupg.org/pipermail/gnupg-announce/2015q1/000361.html https:// • CWE-20: Improper Input Validation •
CVE-2014-3591
https://notcve.org/view.php?id=CVE-2014-3591
Libgcrypt before 1.6.3 and GnuPG before 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proximate attackers to obtain the server's private key by determining factors using crafted ciphertext and the fluctuations in the electromagnetic field during multiplication. Libgcrypt versiones anteriores a 1.6.3 y GnuPG versiones anteriores a 1.4.19, no implementa un blinding de texto cifrado para el desencriptado de Elgamal, lo que permite a atacantes físicamente próximos obtener la clave privada del servidor determinando factores que utilizan texto cifrado y las fluctuaciones en el campo electromagnético durante la multiplicación. • http://www.cs.tau.ac.il/~tromer/radioexp http://www.debian.org/security/2015/dsa-3184 http://www.debian.org/security/2015/dsa-3185 https://lists.gnupg.org/pipermail/gnupg-announce/2015q1/000363.html https://lists.gnupg.org/pipermail/gnupg-announce/2015q1/000364.html • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2015-0837
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) •
