Description Kenneth Russell 2009-12-17 19:01:35 PST
The index validation code added in https://bugs.webkit.org/show_bug.cgi?id=31239 verifies too many indices. It should compute its maximum index from the sub-region of the bound element array buffer indicated by the passed offset and count; instead, it checks all indices in the element array buffer, leading to failures of valid code.
