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.]
