CVE-2018-20184: Buffer Overflow
First published: Mon Dec 17 2018(Updated: )
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.
