Description Guilherme de Almeida Suckevicz 2021-12-23 20:21:40 UTC 
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.

Comment 1 Guilherme de Almeida Suckevicz 2021-12-23 20:21:52 UTC 
Created gegl04 tracking bugs for this issue:

Affects: fedora-all [bug 2035384]
Comment 4 Garrett Tucker 2021-12-24 00:45:46 UTC 
Filed relevant trackers. However, at this time there is no gegl included in RHEL 9. Will keep an eye out for its possible inclusion in the future, but for right now, no effect on RHEL 9.
Comment 5 Josef Ridky 2022-01-04 12:12:09 UTC 
There is no gegl04 in RHEL9 as it is requirement for GIMP package, which is currently unavailable for RHEL-9, once GIMP release new version, gegl04 in version 0.4.34 or higher will become part of RHEL9 as well.
