In the affected versions, `TZInfo::Timezone.get` fails to validate time zone identifiers correctly, allowing a new line character within the identifier. With Ruby version 1.9.3 and later, `TZInfo::Timezone.get` can be made to load unintended files with `require`, executing them within the Ruby process. Versions 0.3.61 and 1.2.10 include fixes to correctly validate time zone identifiers. Versions 2.0.0 and later are not vulnerable. Version 0.3.61 can still load arbitrary files from the Ruby load path if their name follows the rules for a valid time zone identifier and the file has a prefix of `tzinfo/definition` within a directory in the load path. Applications should ensure that untrusted files are not placed in a directory on the load path. As a workaround, the time zone identifier can be validated before passing to `TZInfo::Timezone.get` by ensuring it matches the regular expression `\\\\A[A-Za-z0-9+\\\\-_]+(?:\\\\/[A-Za-z0-9+\\\\-_]+)*\\\\z`.\"},{\"lang\":\"es\",\"value\":\"TZInfo es una biblioteca de Ruby que proporciona acceso a los datos de las zonas horarias y permite convertir las horas usando reglas de zonas horarias. Las versiones anteriores a 0.36.1, as\u00ed como las anteriores a la 1.2.10 cuando son usadas con la fuente de datos de Ruby tzinfo-data, son vulnerables a un salto de ruta relativo. Con la fuente de datos Ruby, las zonas horarias son definidas en archivos Ruby. Se presenta un archivo por zona horaria. Los archivos de zonas horarias se cargan con \\\"require\\\" bajo demanda. En las versiones afectadas, \\\"TZInfo::Timezone.get\\\" no comprueba correctamente los identificadores de zonas horarias, permitiendo un nuevo car\u00e1cter de l\u00ednea dentro del identificador. Con la versi\u00f3n 1.9.3 de Ruby y posteriores, puede hacerse que \\\"TZInfo::Timezone.get\\\" cargue archivos no deseados con \\\"require\\\", ejecut\u00e1ndolos dentro del proceso de Ruby. Las versiones 0.3.61 y 1.2.10 incluyen correcciones para comprender correctamente los identificadores de zona horaria. Las versiones 2.0.0 y posteriores no son vulnerables. La versi\u00f3n 0.3.61 a\u00fan puede cargar archivos arbitrarios desde la ruta de carga de Ruby si su nombre sigue las reglas para un identificador de zona horaria v\u00e1lido y el archivo presenta un prefijo de \\\"tzinfo/definici\u00f3n\\\" dentro de un directorio en la ruta de carga. Las aplicaciones deben asegurarse de que los archivos que no son confiables no sean colocados en un directorio de la ruta de carga. Como mitigaci\u00f3n, el identificador de la zona horaria puede ser comprobado antes de pasarlo a \\\"TZInfo::Timezone.get\\\" asegur\u00e1ndose de que coincide con la expresi\u00f3n regular \\\"A[A-Za-z0-9+\\\\-_]+(?:\\\\/[A-Za-z0-9+\\\\-_]+)*\\\\z\\\"\"}],\"metrics\":{\"cvssMetricV31\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\",\"baseScore\":8.1,\"baseSeverity\":\"HIGH\"},\"exploitabilityScore\":2.2,\"impactScore\":5.9},{\"source\":\"security-advisories@github.com\",\"type\":\"Secondary\",\"cvssData\":{\"version\":\"3.1\",\"vectorString\":\"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H\",\"attackVector\":\"NETWORK\",\"attackComplexity\":\"HIGH\",\"privilegesRequired\":\"NONE\",\"userInteraction\":\"REQUIRED\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\",\"baseScore\":7.5,\"baseSeverity\":\"HIGH\"},\"exploitabilityScore\":1.6,\"impactScore\":5.9}]},\"weaknesses\":[{\"source\":\"security-advisories@github.com\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-22\"},{\"lang\":\"en\",\"value\":\"CWE-23\"}]},{\"source\":\"nvd@nist.gov\",\"type\":\"Secondary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-22\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:tzinfo_project:tzinfo:*:*:*:*:*:*:*:*\",\"versionEndExcluding\":\"0.3.61\",\"matchCriteriaId\":\"E24943A0-7FE6-450E-A961-B572D68FDA1D\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:a:tzinfo_project:tzinfo:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"1.0.0\",\"versionEndExcluding\":\"1.2.10\",\"matchCriteriaId\":\"15610CDB-665E-4C01-9726-2FC9CD0EF71B\"}]}]},{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*\",\"matchCriteriaId\":\"07B237A9-69A3-4A9C-9DA0-4E06BD37AE73\"}]}]}],\"references\":[{\"url\":\"https://github.com/tzinfo/tzinfo/commit/9905ca93abf7bf3e387bd592406e403cd18334c7\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Patch\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/tzinfo/tzinfo/commit/9eddbb5c0e682736f61d0dd803b6031a5db9eadf\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Patch\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/tzinfo/tzinfo/releases/tag/v0.3.61\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Release Notes\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/tzinfo/tzinfo/releases/tag/v1.2.10\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Release Notes\",\"Third Party Advisory\"]},{\"url\":\"https://github.com/tzinfo/tzinfo/security/advisories/GHSA-5cm2-9h8c-rvfx\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Exploit\",\"Third Party Advisory\"]},{\"url\":\"https://lists.debian.org/debian-lts-announce/2022/08/msg00009.html\",\"source\":\"security-advisories@github.com\",\"tags\":[\"Mailing List\",\"Third Party Advisory\"]}]}}"
