CVE-2017-9117: Canonical Ubuntu Linux

Medium severity, CVSS 4.0. EPSS: 2.2% chance of exploitation in the next 30 days.

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).

Affected products

• Canonical Ubuntu Linux: version 14.04 only; version 16.04 only; version 17.10 only
• Libtiff Libtiff: version 4.0.7 only
