+Subject: Bug 790784 - (CVE-2017-17784) heap overread in gbr parser /
+ load_image.
+
+We were assuming the input name was well formed, hence was
+nul-terminated. As any data coming from external input, this has to be
+thorougly checked.
+Similar to commit 06d24a79af94837d615d0024916bb95a01bf3c59 but adapted
+to older gimp-2-8 code.
