[jira] [Created] (HIVE-25617) fix CVE-2020-8908

lujie created HIVE-25617:
----------------------------

             Summary: fix CVE-2020-8908
                 Key: HIVE-25617
                 URL: https://issues.apache.org/jira/browse/HIVE-25617
             Project: Hive
          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.
