+Subject: Bug 739134 - (CVE-2017-17786) Out of bounds read / heap overflow
+ in...
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+... TGA importer.
+
+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
+channel) and 16 bits (5 bits per color channel and 1 bit for alpha), and
+RGB as 15 and 24 bits.
+Maybe there exist more variants, but if they do exist, we simply don't
+support them yet.
+
+Thanks to Hanno Böck for the report and a first patch attempt.
+
+(cherry picked from commit 674b62ad45b6579ec6d7923dc3cb1ef4e8b5498b)
