When supplying a TIFF file that has a tag for one of Make, Model, or Copyright, where the value is exactly 32 bytes (with no null bytes), a buffer over-read occurs. This will cause a crash to happen when compiled with ASAN, or potential data leak when not.

Over read stops at the first \0 encountered. Given the limited impact, there is currently no plan to backport this fix. Affected products may get this patches if PHP packages are rebased to newer upstream version in the future.
