A global buffer overflow in the genmp_writefontmacro_latex component in genmp.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into mp format.

The version of transfig installed on the remote host is prior to 3.2.7b-10.8. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1807 advisory.

    2024-06-07: CVE-2019-19797 was added to this advisory.

    An out-of-bounds write flaw was found in transfig in the way the `fig2dev` program handled the processing     of Fig format files. Specifically, the flaw affects the translation process of Fig codes into the box     graphics language. This flaw allows for potential exploitation by crashing the `fig2dev` program by     tricking it into processing specially crafted Fig format files. (CVE-2019-19797)

    A global buffer overflow in the genmp_writefontmacro_latex component in genmp.c of fig2dev 3.2.7b allows     attackers to cause a denial of service (DOS) via converting a xfig file into mp format. (CVE-2020-21678)

    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. (CVE-2020-21681)

    A global buffer overflow in the set_fill 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. (CVE-2020-21682)

    A global buffer overflow in the shade_or_tint_name_after_declare_color in genpstricks.c of fig2dev 3.2.7b     allows attackers to cause a denial of service (DOS) via converting a xfig file into pstricks format.
    (CVE-2020-21683)

    A global buffer overflow in the put_font in genpict2e.c of fig2dev 3.2.7b allows attackers to cause a     denial of service (DOS) via converting a xfig file into pict2e format. (CVE-2020-21684)

    An issue was discovered in fig2dev before 3.2.8.. A NULL pointer dereference exists in the function     compute_closed_spline() located in trans_spline.c. It allows an attacker to cause Denial of Service. The     fixed version of fig2dev is 3.2.8. (CVE-2021-32280)
