+Subject: ft: Use FT_Done_MM_Var instead of free when available in
+ cairo_ft_apply_variations
+
+Fixes a crash when using freetype >= 2.9
+
+[This is considered to be security-sensitive because WebKitGTK+ sets its
+own memory allocator, which is not compatible with system free(), making
+this a remotely triggerable denial of service or memory corruption.]
