From 5d28011c40ec86cf52cffad541093d37c263898a Mon Sep 17 00:00:00 2001 From: Dan Fandrich Date: Fri, 20 Apr 2018 18:05:19 +0200 Subject: [PATCH] Reduce maximum recursion depth in exif_data_load_data_content This only needs to be a small, single digit integer for normal files, and reducing the maximum closer to this reduces the time and space needed to detect pathological cases.
