+We were assuming the input name was well formed, hence was

+thorougly checked.
+Similar to commit 06d24a79af94837d615d0024916bb95a01bf3c59 but adapted
+to older gimp-2-8 code.

+Subject: [PATCH] Bug 739133 - (CVE-2017-17785) Heap overflow while parsing FLI
+ files.
+
+It is possible to trigger a heap overflow while parsing FLI files. The
+RLE decoder is vulnerable to out of boundary writes due to lack of
+boundary checks.
+
+The variable "framebuf" points to a memory area which was allocated
+with fli_header->width * fli_header->height bytes. The RLE decoder
+therefore must never write beyond that limit.
+
+If an illegal frame is detected, the parser won't stop, which means
+that the next valid sequence is properly parsed again. This should
+allow GIMP to parse FLI files as good as possible even if they are
+broken by an attacker or by accident.
+
+While at it, I changed the variable xc to be of type size_t, because
+the multiplication of width and height could overflow a 16 bit type.
+

+Be more thorough on valid TGA RGB and RGBA images.
+In particular current TGA plug-in can import RGBA as 32 bits (8 bits per

+RGB as 15 and 24 bits.
+Maybe there exist more variants, but if they do exist, we simply don't
