Last modified Jun 17, 2026

CVE-2017-9117 is a medium-severity vulnerability rated 4/10 on the CVSS scale. In LibTIFF 4.0.6 and possibly other versions, the program processes BMP images without verifying that biWidth and biHeight in the bitmap-information header match the actual input, as demonstrated by a heap-based buffer over-read in bmp2tiff. NOTE: mentioning bmp2tiff does not imply that the activation point is in the bmp2tiff.c file (which was removed before the 4.0.7 release).. EPSS estimates a 2.22% chance of exploitation in the next 30 days.
