Description Prasad J Pandit 2015-09-23 06:18:35 EDT

Security researcher David Chan reported that Mozilla's mozTCPSocket
implementation could leak data past the end of an array allowing for the
potential exposure of memory or private data to malicious servers.

This feature is used by Firefox OS and is disabled by default in Firefox on
other operating systems.
