"The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by a vulnerability as
referenced in the SUSE-SU-2023:1756-1 advisory.

  - A vulnerability was discovered in ImageMagick where a specially created SVG file loads itself and causes a
    segmentation fault. This flaw allows a remote attacker to pass a specially crafted SVG file that leads to
    a segmentation fault, generating many trash files in /tmp, resulting in a denial of service. When
    ImageMagick crashes, it generates a lot of trash files. These trash files can be large if the SVG file
    contains many render actions. In a denial of service attack, if a remote attacker uploads an SVG file of
    size t, ImageMagick generates files of size 103*t. If an attacker uploads a 100M SVG, the server will
    generate about 10G. (CVE-2023-1289)

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