CVE-2018-20184 is a vulnerability of currently unknown severity. In GraphicsMagick 1.4 snapshot-20181209 Q8, there is a heap-based buffer overflow in the WriteTGAImage function of tga.c, which allows attackers to cause a denial of service via a crafted image file, because the number of rows or columns can exceed the pixel-dimension restrictions of the TGA specification.. EPSS estimates a 2.31% chance of exploitation in the next 30 days.
