CVE-2018-20185 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. In GraphicsMagick 1.4 snapshot-20181209 Q8 on 32-bit platforms, there is a heap-based buffer over-read in the ReadBMPImage function of bmp.c, which allows attackers to cause a denial of service via a crafted bmp image file. This only affects GraphicsMagick installations with customized BMP limits.. EPSS estimates a 2.11% chance of exploitation in the next 30 days.
