CVSS: 5.0EPSS: 2%CPEs: 2EXPL: 1CVE-2009-1904 – ruby: DoS vulnerability in BigDecimal
https://notcve.org/view.php?id=CVE-2009-1904
The BigDecimal library in Ruby 1.8.6 before p369 and 1.8.7 before p173 allows context-dependent attackers to cause a denial of service (application crash) via a string argument that represents a large number, as demonstrated by an attempted conversion to the Float data type. La librería BigDecimal en Ruby v1.8.6 anteriores p369 y v1.8.7, anteriores a p173 permite a los atacantes dependientes del contexto causar una denegación de servicio (caída de la aplicación) a través de un argumento de cadena de caracteres que representa un número largo, como se demuestra por un intento de conversión al tipo de dato Float. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=532689 http://bugs.gentoo.org/show_bug.cgi?id=273213 http://github.com/NZKoz/bigdecimal-segfault-fix/tree/master http://groups.google.com/group/rubyonrails-security/msg/fad60751e2b9b4f6?dmode=source http://lists.apple.com/archives/security-announce/2010//Mar/msg00001.html http://mail-index.netbsd.org/pkgsrc-changes/2009/06/10/msg024708.html http://osvdb.org/55031 http://redmine.ruby-lang.org/issues/show/794 http://secunia.c • CWE-189: Numeric Errors •

ext/openssl/ossl_ocsp.c in Ruby 1.8 and 1.9 does not properly check the return value from the OCSP_basic_verify function, which might allow remote attackers to successfully present an invalid X.509 certificate, possibly involving a revoked certificate. ext/openssl/ossl_ocsp.c en Ruby v1.8 y v1.9 no comprueba adecuadamente el valor de retorno de la funcion OCSP_basic_verify, lo cual permitiria a atacantes remotos tener exito en la presentacion de un certificado X.509 invalido, posiblemente utilizando un certificado revocado. • http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=513528 http://redmine.ruby-lang.org/issues/show/1091 http://secunia.com/advisories/33750 http://secunia.com/advisories/35699 http://secunia.com/advisories/35937 http://www.mandriva.com/security/advisories?name=MDVSA-2009:193 http://www.redhat.com/support/errata/RHSA-2009-1140.html http://www.securityfocus.com/bid/33769 http://www.securitytracker.com/id?1022505 http://www.ubuntu.com/usn/USN-805-1 https://exchange.xfor • CWE-287: Improper Authentication •

https://notcve.org/view.php?id=CVE-2008-4310
httputils.rb in WEBrick in Ruby 1.8.1 and 1.8.5, as used in Red Hat Enterprise Linux 4 and 5, allows remote attackers to cause a denial of service (CPU consumption) via a crafted HTTP request. NOTE: this issue exists because of an incomplete fix for CVE-2008-3656. El archivo httputils.rb en WEBrick en Ruby versiones 1.8.1 y 1.8.5, tal y como es usado en versiones 4 y 5 de Red Hat Enterprise Linux, permite a los atacantes remotos causar una denegación de servicio (consumo de CPU) por medio de una petición HTTP diseñada. NOTA: este problema se presenta debido a una corrección incompleta del CVE-2008-3656. • https://www.exploit-db.com/exploits/32222 http://secunia.com/advisories/33013 http://www.openwall.com/lists/oss-security/2008/12/04/2 http://www.redhat.com/support/errata/RHSA-2008-0981.html https://bugzilla.redhat.com/show_bug.cgi?id=470252 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A10250 https://access.redhat.com/security/cve/CVE-2008-4310 • CWE-399: Resource Management Errors •
