https://notcve.org/view.php?id=CVE-2013-4073
The OpenSSL::SSL.verify_certificate_identity function in lib/openssl/ssl.rb in Ruby 1.8 before 1.8.7-p374, 1.9 before 1.9.3-p448, and 2.0 before 2.0.0-p247 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. La función OpenSSL::SSL.verify_certificate_identity en lib/openssl/ssl.rb en Ruby v1.8 anterior a v1.8.7-p374, v1.9 anterior a v1.9.3-p448, y v2.0 anterior a v2.0.0-p247 no manejar adecuadamente un carácter “\0” en un nombre de dominio en el campo Subject Alternative Name de un certificado X.509, lo que permite a atacantes "man-in-the-middle" suplantar servidores SSL de su elección mediante un certificado manipulado expedido por una Autoridad Certificadora legítima, un problema relacionado con CVE-2009-2408. • http://forums.interworx.com/threads/8000-InterWorx-Version-5-0-14-Released-on-Beta-Channel%21 http://lists.apple.com/archives/security-announce/2013/Oct/msg00004.html http://lists.opensuse.org/opensuse-updates/2013-07/msg00042.html http://lists.opensuse.org/opensuse-updates/2013-07/msg00044.html http://rhn.redhat.com/errata/RHSA-2013-1090.html http://rhn.redhat.com/errata/RHSA-2013-1103.html http://rhn.redhat.com/errata/RHSA-2013-1137.html http://support.apple.com/kb/HT6150 • CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2012-5371
Ruby (aka CRuby) 1.9 before 1.9.3-p327 and 2.0 before r37575 computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table, as demonstrated by a universal multicollision attack against a variant of the MurmurHash2 algorithm, a different vulnerability than CVE-2011-4815. Ruby (también conocido como CRuby) v1.9 anteriores a v1.9.3-p327 y v2.0 anteriores a r37575 calcula los valores de hash sin restringir la posibilidad de provocar colisiones hash previsibles, lo que permite a atacantes dependientes de contexto provocar una denegación de servicio (consumo de CPU) a través de la manipulación de una entrada para la aplicación que mantiene la tabla de valores hash, como lo demuestra un ataque universal multicolision contra una variante del algoritmo MurmurHash2, una vulnerabilidad diferente a CVE-2011-4815. • http://2012.appsec-forum.ch/conferences/#c17 http://asfws12.files.wordpress.com/2012/11/asfws2012-jean_philippe_aumasson-martin_bosslet-hash_flooding_dos_reloaded.pdf http://secunia.com/advisories/51253 http://securitytracker.com/id?1027747 http://www.ocert.org/advisories/ocert-2012-001.html http://www.osvdb.org/87280 http://www.ruby-lang.org/en/news/2012/11/09/ruby19-hashdos-cve-2012-5371 http://www.securityfocus.com/bid/56484 http://www.ubuntu.com/usn/USN-1733-1 http • CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2012-4481
The safe-level feature in Ruby 1.8.7 allows context-dependent attackers to modify strings via the NameError#to_s method when operating on Ruby objects. NOTE: this issue is due to an incomplete fix for CVE-2011-1005. La funcionalidad safe-level de Ruby v1.8.7 permite a atacantes dependiendo del contexto modificar cadenas a través del método NameError#to_s mientras corren objetos Ruby.

Ruby 1.8.7 before patchlevel 371, 1.9.3 before patchlevel 286, and 2.0 before revision r37068 allows context-dependent attackers to bypass safe-level restrictions and modify untainted strings via the name_err_mesg_to_str API function, which marks the string as tainted, a different vulnerability than CVE-2011-1005. Ruby v1.8.7 antes de patchlevel 371, v1.9.3 antes patchlevel 286 y v2.0 antes de la revisión r37068 permite a atacantes dependientes de contexto evitar las restricciones de seguridad de nivel y modificar cadenas untainted a través de la función de la API name_err_mesg_to_str, que marca la cadena como contaminada, una diferente vulnerabilidad a CVE-2011-1005. • http://lists.fedoraproject.org/pipermail/package-announce/2012-October/089554.html http://lists.fedoraproject.org/pipermail/package-announce/2012-October/089887.html http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=37068 http://www.mandriva.com/security/advisories?name=MDVSA-2013:124 http://www.openwall.com/lists/oss-security/2012/10/02/4 http://www.openwall.com/lists/oss-security/2012/10/03/9 http://www.ruby-lang.org/en/news/2012/10/12/cve-2012-4464-cve- • CWE-264: Permissions, Privileges, and Access Controls CWE-266: Incorrect Privilege Assignment •
