"According to the versions of the ImageMagick packages installed, the EulerOS installation on the remote host is affected
by the following vulnerabilities :

  - The ReadTIFFImage function in coders/tiff.c in ImageMagick 7.0.7-26 Q16 does not properly restrict memory
    allocation, leading to a heap-based buffer over-read. (CVE-2018-8960)

  - In ImageMagick 7.0.8-43 Q16, there is a heap-based buffer over-read in the function WritePNGImage of
    coders/png.c, related to Magick_png_write_raw_profile and LocaleNCompare. (CVE-2019-19949)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
