Resolution ========== Upgrade to 9.54.0-3. # pacman -Syu "ghostscript>=9.54.0-3" The problem has been fixed upstream but no release is available yet. Workaround ========== None. Description =========== A trivial sandbox (enabled with the -dSAFER option) escape security issue was found in the ghostscript interpreter by injecting a specially crafted pipe command.
