The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3585-1 advisory.
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)
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)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
