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-2014-4617

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 •
CVE-2013-4576 – gnupg: RSA secret key recovery via acoustic cryptanalysis
https://notcve.org/view.php?id=CVE-2013-4576
GnuPG 1.x before 1.4.16 generates RSA keys using sequences of introductions with certain patterns that introduce a side channel, which allows physically proximate attackers to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryption. NOTE: applications are not typically expected to protect themselves from acoustic side-channel attacks, since this is arguably the responsibility of the physical device. Accordingly, issues of this type would not normally receive a CVE identifier. However, for this issue, the developer has specified a security policy in which GnuPG should offer side-channel resistance, and developer-specified security-policy violations are within the scope of CVE. GnuPG 1.x anteriores a 1.4.16 genera claves RSA utilizando secuencias de introducciones con ciertos patrones que introducen un ataque de canal lateral, lo cual permite a atacantes físicamente próximos extraer claves RSA a través de un ataque de texto cifrado elegido y criptoanálisis acústico durante el descifrado. • http://lists.gnupg.org/pipermail/gnupg-devel/2013-December/028102.html http://osvdb.org/101170 http://rhn.redhat.com/errata/RHSA-2014-0016.html http://seclists.org/oss-sec/2013/q4/520 http://seclists.org/oss-sec/2013/q4/523 http://www.cs.tau.ac.il/~tromer/acoustic http://www.debian.org/security/2013/dsa-2821 http://www.securityfocus.com/bid/64424 http://www.securitytracker.com/id/1029513 http://www.tau.ac.il/~tromer/papers/acoustic-20131218.pdf ht • CWE-255: Credentials Management Errors •
CVE-2013-4351 – gnupg: treats no-usage-permitted keys as all-usages-permitted
https://notcve.org/view.php?id=CVE-2013-4351
GnuPG 1.4.x, 2.0.x, and 2.1.x treats a key flags subpacket with all bits cleared (no usage permitted) as if it has all bits set (all usage permitted), which might allow remote attackers to bypass intended cryptographic protection mechanisms by leveraging the subkey. GnuPG 1.4.x, y 2.1.x trata un subpaquete de flags clave con todos los bits a 0 (sin uso permitido) como si tuviera todos los bits establecidos (todo uso permitido) lo que permitiría a atacantes remotos evadir mecanismos de protección criptográfica intencionada mediante el aprovechamiento de la subclave. • http://lists.opensuse.org/opensuse-updates/2013-10/msg00003.html http://lists.opensuse.org/opensuse-updates/2013-10/msg00006.html http://rhn.redhat.com/errata/RHSA-2013-1459.html http://thread.gmane.org/gmane.comp.encryption.gpg.devel/17712/focus=18138 http://ubuntu.com/usn/usn-1987-1 http://www.debian.org/security/2013/dsa-2773 http://www.debian.org/security/2013/dsa-2774 http://www.openwall.com/lists/oss-security/2013/09/13/4 https://bugzilla.redhat.com/show_ • CWE-310: Cryptographic Issues •
