Gradle vulnerable to local privilege escalation through system temporary directory

Type: advisorySources: OSV

Gradle is a build automation tool, and its native-platform tool provides Java bindings for native APIs. On Unix-like systems, the system temporary directory can be created with open permissions that allow multiple users to create and delete files within it. This library initialization could be vulnerable to a local privilege escalation from an attacker quickly deleting and recreating files in the system temporary directory. Gradle builds that rely on versions of net.rubygrapefruit:native-platform prior to 0.22-milestone-28 could be vulnerable to a local privilege escalation from an attacker quickly deleting and recreating files in the system temporary directory. In net.rubygrapefruit:native-platform prior to version 0.22-milestone-28, if the `Native.get(Class<>)` method was called, without calling `Native.init(File)` first, with a non-`null` argument used as working file path, then the library would initialize itself using the system temporary directory and NativeLibraryLocator.java lines 68 through 78. Version 0.22-milestone-28 has been released with changes that fix the problem. Initialization is now mandatory and no longer uses the system temporary directory, unless such a path is passed for initialization. The only workaround for affected versions is to make sure to do a proper initialization, using a location that is safe. Gradle 8.12, only that exact version, had codepaths where the initialization of the underlying native integration library took a default path, relying
