See below for more detailed information:\n* Red Hat Enterprise Linux 8 - `libcroco` is a runtime dependency of `gnome-shell`, `gettext` and `inkscape`.\n* Red Hat Enterprise Linux 7 - `libcroco` is a runtime dependency of `gnome-shell`, `gettext`, `librsvg2` and `inkscape`.\n* Red Hat Enterprise Linux 6 - `libcroco` is required by `firefox` to bundle `gtk3` but `firefox` does not use `libcroco` as its CSS parsing engine or provide gtk3 to other packages, and thus not affected. `libcroco` is a runtime dependency of `inkscape`, `librsvg2` and `gettext`.\nThis flaw has only been demonstrated to cause a crash, but if there is any concern of further exploitation beyond that, Red Hat Enterprise Linux 6, 7, and 8 packages are built with a stack protector and stack ASLR which would significantly reduce the likelihood of further exploitation.", "threat_severity": "Moderate"}
