CVE-2019-3894 (CCN-160613)

Assigned:2019-04-30
Published:2019-04-30
Updated:2020-10-15
Summary: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.
