------------------------------
Summary: Do not use guava's Files.createTempDir()
Key: PHOENIX-6576
URL: https://issues.apache.org/jira/browse/PHOENIX-6576
Project: Phoenix
Issue Type: Bug
Reporter: lujie
see [https://www.cvedetails.com/cve/CVE-2020-8908/]
A temp directory creation vulnerability exists in all versions of Guava,
allowing an attacker with access to the machine to potentially access data in a
temporary directory created by the Guava API
com.google.common.io.Files.createTempDir(). By default, on unix-like systems,
the created directory is world-readable (readable by an attacker with access to
the system). The method in question has been marked
[@deprecated|https://github.com/deprecated] in versions 30.0 and later and
should not be used. For Android developers, we recommend choosing a temporary
directory API provided by Android, such as context.getCacheDir(). For other
Java developers, we recommend migrating to the Java 7 API
java.nio.file.Files.createTempDirectory() which explicitly configures
permissions of 700, or configuring the Java runtime's java.io.tmpdir system
property to point to a location whose permissions are appropriately configured.
