"The remote SUSE Linux SUSE15 host has a package installed that is affected by multiple vulnerabilities as referenced in
the openSUSE-SU-2021:1143-1 advisory.

  - Xfig fig2dev 3.2.7a has a stack-based buffer overflow in the calc_arrow function in bound.c.
    (CVE-2019-14275)

  - read_textobject in read.c in Xfig fig2dev 3.2.7b has a stack-based buffer overflow because of an incorrect
    sscanf. (CVE-2019-19555)

  - 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. (CVE-2019-19746)

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

  - 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)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
