+Subject: [PATCH] CVE-2023-25433
+
+tiffcrop correctly update buffersize after rotateImage()
+fix#520 rotateImage() set up a new buffer and calculates its size
+individually. Therefore, seg_buffs[] size needs to be updated accordingly.
+Before this fix, the seg_buffs buffer size was calculated with a different
+formula than within rotateImage().
+
+Closes #520.
