CVSS: 5.0EPSS: 0%CPEs: 34EXPL: 0CVE-2012-4466 – ruby: safe level bypass via name_err_mesg_to_str()
https://notcve.org/view.php?id=CVE-2012-4466
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 •

https://notcve.org/view.php?id=CVE-2011-2705
The SecureRandom.random_bytes function in lib/securerandom.rb in Ruby before 1.8.7-p352 and 1.9.x before 1.9.2-p290 relies on PID values for initialization, which makes it easier for context-dependent attackers to predict the result string by leveraging knowledge of random strings obtained in an earlier process with the same PID. La función SecureRandom.random_bytes de lib/securerandom.rb de Ruby en versiones anteriores a 1.8.7-p352 y 1.9.x anteriores a 1.9.2-p290 se basa en valores PID para la inicialización, lo que facilita a atacantes dependientes del contexto predecir la cadena resultado utilizando el conocimiento de cadenas aleatorias obtenidas en procesos anteriores con el mismo PID. • http://lists.fedoraproject.org/pipermail/package-announce/2011-July/063062.html http://lists.fedoraproject.org/pipermail/package-announce/2011-July/063071.html http://redmine.ruby-lang.org/issues/4579 http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=32050 http://svn.ruby-lang.org/repos/ruby/tags/v1_8_7_352/ChangeLog http://svn.ruby-lang.org/repos/ruby/tags/v1_9_2_290/ChangeLog http://www.openwall.com/lists/oss-security/2011/07/11/1 http://www.ope • CWE-20: Improper Input Validation •
CVSS: 6.8EPSS: 2%CPEs: 38EXPL: 0CVE-2011-0188 – ruby: memory corruption in BigDecimal on 64bit platforms
https://notcve.org/view.php?id=CVE-2011-0188
The VpMemAlloc function in bigdecimal.c in the BigDecimal class in Ruby 1.9.2-p136 and earlier, as used on Apple Mac OS X before 10.6.7 and other platforms, does not properly allocate memory, which allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving creation of a large BigDecimal value within a 64-bit process, related to an "integer truncation issue." La función VpMemAlloc en bigdecimal.c en la clase BigDecimal en Ruby v1.9.2-P136 y anteriores, tal como se utiliza en Apple Mac OS X antes de vv10.6.7 y en otras plataformas, no asigna memoria adecuadamente, lo que permite a atacantes dependientes de contexto ejecutar código de su elección o causar una denegación de servicio (caída de aplicación) a través de vectores que impliquen la creación de un valor BigDecimal grande dentro de un proceso de 64 bits, relacionado con un "fallo de truncado de entero". • http://lists.apple.com/archives/security-announce/2011/Mar/msg00006.html http://support.apple.com/kb/HT4581 http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/trunk/ext/bigdecimal/bigdecimal.c?r1=29364&r2=30993 http://www.mandriva.com/security/advisories?name=MDVSA-2011:097 http://www.mandriva.com/security/advisories?name=MDVSA-2011:098 http://www.redhat.com/support/errata/RHSA-2011-0908.html http://www.redhat.com/support/errata/RHSA-2011-0909.html http://www.redhat.com/support/ • CWE-189: Numeric Errors •
