+Subject: [PATCH 1/2] convertbmp: detect invalid file dimensions early
+
+width/length dimensions read from bmp headers are not necessarily
+valid. For instance they may have been maliciously set to very large
+values with the intention to cause DoS (large memory allocation, stack
+overflow). In these cases we want to detect the invalid size as early
+as possible.
+
+This commit introduces a counter which verifies that the number of
+written bytes corresponds to the advertized width/length.
+
+See commit 8ee335227bbc for details.
