A stack-based buffer overflow in the genptk_text component in genptk.c of fig2dev 3.2.7b allows attackers to cause a denial of service (DOS) via converting a xfig file into ptk format.

This plugin has been deprecated as it does not adhere to established standards for this style of check.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5864-1 advisory.

    Frederic Cambus discovered that Fig2dev incorrectly handled certain image files. If a user or an automated     system were tricked into opening a certain

    specially crafted input file, a remote attacker could possibly use this issue to cause a denial of     service. This issue only affected Ubuntu 18.04 LTS. (CVE-2019-14275)

    It was discovered that Fig2dev incorrectly handled certain image files. If

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2778 advisory.

  - read_colordef in read.c in Xfig fig2dev 3.2.7b has an out-of-bounds write. (CVE-2019-19797)

  - fig2dev 3.2.7b contains a stack buffer overflow in the bezier_spline function in genepic.c.
    (CVE-2020-21529)

  - fig2dev 3.2.7b contains a segmentation fault in the read_objects function in read.c. (CVE-2020-21530)

  - fig2dev 3.2.7b contains a global buffer overflow in the conv_pattern_index function in gencgm.c.
    (CVE-2020-21531)

  - fig2dev 3.2.7b contains a global buffer overflow in the setfigfont function in genepic.c. (CVE-2020-21532)

  - fig2dev 3.2.7b contains a stack buffer overflow in the read_textobject function in read.c.
    (CVE-2020-21533)

  - fig2dev 3.2.7b contains a global buffer overflow in the get_line function in read.c. (CVE-2020-21534)

  - fig2dev 3.2.7b contains a segmentation fault in the gencgm_start function in gencgm.c. (CVE-2020-21535)

  - A stack-based buffer overflow in the genptk_text component in genptk.c of fig2dev 3.2.7b allows attackers     to cause a denial of service (DOS) via converting a xfig file into ptk format. (CVE-2020-21675)

  - A stack-based buffer overflow in the genpstrx_text() component 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-2020-21676)

  - 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)

  - An Out of Bounds flaw was found fig2dev version 3.2.8a. A flawed bounds check in read_objects() could     allow an attacker to provide a crafted malicious input causing the application to either crash or in some     cases cause memory corruption. The highest threat from this vulnerability is to integrity as well as     system availability. (CVE-2021-3561)
