CVE-2018-19876
cairo 1.16.0, in cairo_ft_apply_variations() in cairo-ft-font.c, would free memory using a free function incompatible with WebKit's fastMalloc, leading to an application crash with a "free(): invalid pointer" error.
Does this matter?
Lower severity and a low EPSS score (1.71%). Track it; it rarely justifies an emergency change on its own.
