Created libvpx tracking bugs for this issue:

Affects: fedora-all [bug 1486855]

Comment 2 Huzaifa S. Sidhpurwala 2017-08-31 06:07:12 UTC

Analysis:

This is essentially an application crash caused due to parsing large files. The patch ensures that when libvpx is compiled it can only process smaller files.
