Comment 1 Tomas Hoger 2016-06-06 16:07:34 EDT

imagescale() function was only introduced in PHP 5.5, hence older are not affected.

Comment 2 Tomas Hoger 2016-06-08 07:58:32 EDT

This is a limited 8 byte (sizeof(double)) buffer over-read.  In standard non-ASAN builds, it's very unlikely to cause crash.  This does not have any real practical impact.
