Subject: potrace: multiple crashes
Hello,
the past year I discovered and documented multiple crashes in potrace:
https://blogs.gentoo.org/ago/2016/08/08/potrace-multiple-three-null-pointer-dereference-in-bm_readbody_bmp-bitmap_io-c/
https://blogs.gentoo.org/ago/2016/08/08/potrace-divide-by-zero-in-bm_new-bitmap-h/
https://blogs.gentoo.org/ago/2016/08/08/potrace-multiplesix-heap-based-buffer-overflow-in-bm_readbody_bmp-bitmap_io-c/
It could be obvious but each crash comes up from a different crafted
image.
If you think that something is suitable for an identifier, please assign it.
Thanks
