lujie updated YARN-10980:
-------------------------
Description:
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 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.
