CVE-2020-11979 – ant: insecure temporary file

https://notcve.org/view.php?id=CVE-2020-11979

As mitigation for CVE-2020-1945 Apache Ant 1.10.8 changed the permissions of temporary files it created so that only the current user was allowed to access them. Unfortunately the fixcrlf task deleted the temporary file and created a new one without said protection, effectively nullifying the effort. This would still allow an attacker to inject modified source files into the build process. Como mitigación para CVE-2020-1945, Apache Ant versión 1.10.8, cambió los permisos de los archivos temporales que creó para que solo el usuario actual pudiera acceder a ellos. Desafortunadamente, la tarea fixcrlf eliminó el archivo temporal y creó uno nuevo sin dicha protección, anulando efectivamente el esfuerzo. • https://github.com/gradle/gradle/security/advisories/GHSA-j45w-qrgf-25vm https://lists.apache.org/thread.html/r107ea1b1a7a214bc72fe1a04207546ccef542146ae22952e1013b5cc%40%3Cdev.creadur.apache.org%3E https://lists.apache.org/thread.html/r1dc8518dc99c42ecca5ff82d0d2de64cd5d3a4fa691eb9ee0304781e%40%3Cdev.creadur.apache.org%3E https://lists.apache.org/thread.html/r2306b67f20c24942b872b0a41fbdc9330e8467388158bcd19c1094e0%40%3Cdev.creadur.apache.org%3E https://lists.apache.org/thread.html/r4ca33fad3fb39d130cda287d5a60727d9e706e6f2cf2339b95729490%40%3Cdev.creadur.apache.org%3E https • CWE-377: Insecure Temporary File CWE-379: Creation of Temporary File in Directory with Insecure Permissions •
