Description Laura Pardo 2018-12-06 17:37:46 UTC 
A flaw was found in Jenkins. The form validation for cron expressions (e.g. "Poll SCM", "Build periodically") could enter infinite loops when cron expressions only matching certain rare dates were entered, blocking request handling threads indefinitely.
