Description Prasad J Pandit 2015-09-22 07:00:07 EDT
Security researcher 'Looben Yang' discovered a use-after-free vulnerability
when using a shared worker with IndexedDB due to a race condition with the
worker. This results in a potentially exploitable crash that can be triggered
through web content.
