Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Local Temp Directory Hijacking Vulnerability

Impact

On Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.

Additionally, any user code uses of WebAppContext::getTempDirectory would similarly be vulnerable.

Additionally, any user application code using the ServletContext attribute for the tempdir will also be impacted. See: https://javaee.github.io/javaee-spec/javadocs/javax/servlet/ServletContext.html#TEMPDIR

For example:

import java.io.File;
import java.io.IOException;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class ExampleServlet extends HttpServlet {
@Override
</tr></table> ... (truncated)
