The bm_readbody_bmp function in bitmap_io.c in potrace before 1.13 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted BMP image, a different vulnerability than CVE-2016-8694 and CVE-2016-8696.
The product dereferences a pointer that it expects to be valid but is NULL.
