CVE-2021-45463 is a high-severity flaw (CVSS 7.8) affecting gegl, gimp, enterprise linux. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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.
