Gradle builds could be vulnerable to a local privilege escalation from an attacker quickly deleting and recreating files in the system temporary directory. This vulnerability impacted builds using precompiled script plugins written in Kotlin DSL and tests for Gradle plugins written using ProjectBuilder or TestKit. If you are on Windows or modern versions of macOS, you are not vulnerable. If you are on a Unix-like operating system with the \"sticky\" bit set on your system temporary directory, you are not vulnerable. The problem has been patched and released with Gradle 7.0. As a workaround, on Unix-like operating systems, ensure that the \"sticky\" bit is set. This only allows the original user (or root) to delete a file. If you are unable to change the permissions of the system temporary directory, you can move the Java temporary directory by setting the System Property `java.io.tmpdir`. The new path needs to limit permissions to the build user only. For additional details refer to the referenced GitHub Security Advisory."}, {"lang": "es", "value": "En Gradle versiones anteriores a 7.0, en sistemas similares a Unix, el directorio temporal del sistema puede ser creado con permisos abiertos que permiten a varios usuarios crear y eliminar archivos dentro de \u00e9l. Las compilaciones de Gradle podr\u00edan ser vulnerables a una escalada de privilegios local de un atacante que elimine y vuelva a crear r\u00e1pidamente archivos en el directorio temporal del sistema. Esta vulnerabilidad afect\u00f3 las compilaciones que usan plugins de script precompilados escritos en Kotlin DSL y pruebas para plugins de Gradle escritos con ProjectBuilder o TestKit. Si tiene Windows o versiones modernas de macOS, no es vulnerable. Si est\u00e1 en un sistema operativo similar a Unix con el bit \"sticky\" configurado en el directorio temporal de su sistema, no es vulnerable. El problema se ha corregido y publicado con Gradle 7.0. Como soluci\u00f3n alternativa, en sistemas operativos similares a Unix, aseg\u00farese de que el bit \"sticky\" est\u00e1 establecido. Esto solo permite que el usuario original (o root) elimine un archivo. Si no puede cambiar los permisos del directorio temporal del sistema, puede mover el directorio temporal de Java configurando la propiedad del sistema `java.io.tmpdir`. La nueva ruta debe limitar los permisos solo al usuario de la compilaci\u00f3n. Para obtener detalles adicionales, consulte el Aviso de Seguridad de GitHub al que se hace referencia"}], "lastModified": "2021-10-20T14:35:05.453", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:gradle:gradle:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "1CBD5FF7-3589-474C-8BA7-0385D3E4BC0F", "versionEndExcluding": "7.0"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:quarkus:quarkus:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "EF712520-1CFD-473A-B3F5-3CDDFE9C2C9A", "versionEndIncluding": "2.2.3"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
