Description Huzaifa S. Sidhpurwala 2015-03-21 11:29:14 UTC
Security researcher ilxu1a reported, through HP Zero Day Initiative's Pwn2Own contest, a flaw in Mozilla's implementation of typed array bounds checking in JavaScript just-in-time compilation (JIT) and its management of bounds checking for heap access. This flaw can be leveraged into the reading and writing of memory allowing for arbitary code execution on the local system.

Red Hat would like to thank the Mozilla project for reporting this issue. Upstream acknowledges ilxu1a as the original reporter.
