According to the versions of the gegl package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  • load_cache in GEGL before 0.4.34 allows shell expansion when a pathname in a constructed command line is not escaped or filtered. This is caused by use of the system library function for execution of the ImageMagick convert fallback in magick-load. NOTE: GEGL releases before 0.4.34 are used in GIMP releases before 2.10.30; however, this does not imply that GIMP builds enable the vulnerable feature.
    (CVE-2021-45463)

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.
