The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3124-1 advisory.
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)
A stack-based buffer overflow in the put_arrow() component 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-2020-21680)
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)
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 these issues but has instead relied only on the application’s self-reported version number.
