CVE-2019-3894: Red Hat JBoss Enterprise Application Platform

High severity, CVSS 8.8. EPSS: 1.5% chance of exploitation in the next 30 days.

It was discovered that the ElytronManagedThread in Wildfly's Elytron subsystem in versions from 11 to 16 stores a SecurityIdentity to run the thread as. These threads do not necessarily terminate if the keep alive time has not expired. This could allow a shared thread to use the wrong security identity when executing.

Affected products

• Red Hat JBoss Enterprise Application Platform: version 7.0.0 only
• Red Hat Wildfly: from 11.0.0, up to and including 16.0.0
