Description Michael Kaplan 2021-08-11 18:10:23 UTC 
A global buffer overflow in the set_color component in genge.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into ge format.

Comment 1 Garrett Tucker 2021-08-26 21:37:25 UTC 
A buffer overflow was possible when choosing the default color when converting to ge. The value associated with the default color enabled access of the array outside of the intended range and would result in a DoS. This has been remediated in: https://sourceforge.net/p/mcj/fig2dev/ci/4d4e1fdac467c386cba8706aa0067d5ab8da02d7/
