There is no fixed version for jetty:jetty
.
Overview
jetty:jetty is an old release of jetty. This artifact has been moved to org.mortbay.jetty:jetty.
Affected versions of this package are vulnerable to Privilege Escalation. 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.
