Description Andrej Nemec 2016-05-12 08:31:14 UTC 
The following flaw was found in Jenkins:

By changing the freely editable 'full name', malicious users with multiple user accounts could prevent other users from logging in, as 'full name' was resolved before actual user name to determine which account is currently trying to log in.
