Detailsinfo

A vulnerability, which was classified as critical, has been found in GEGL up to 0.4.33. This issue affects an unknown function of the component Command Line Handler. The manipulation with an unknown input leads to a argument injection vulnerability. Using CWE to declare the problem leads to CWE-88. The product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.
