Description Guilherme de Almeida Suckevicz 2019-12-30 14:41:53 UTC 
make_arrow in arrow.c in Xfig fig2dev 3.2.7b allows a segmentation fault and out-of-bounds write because of an integer overflow via a large arrow type.

Comment 1 Guilherme de Almeida Suckevicz 2019-12-30 14:43:24 UTC 
Created xfig tracking bugs for this issue:

Affects: epel-7 [bug 1787042]
Affects: fedora-all [bug 1787041]
Comment 2 Hans de Goede 2020-01-15 19:48:45 UTC 
fig2dev is part of transfig, not xfig.

I've update the Fedora tracking bug accordingly, EPEL does not appear to have transfig, so I believe that the EPEL tracking bug can be closed, but I'm leaving that up to you.

I'm also leaving any necessary updates to this bug (Summary?) up to you.
Comment 3 Guilherme de Almeida Suckevicz 2020-01-16 14:58:05 UTC 
Thank you for this information.
I fixed the names for this bug and closed the EPEL as notabug, I will update the other bugs as well.
