ebraminio 70202983f5 [ci] Disable vcpkg freetype installation and fix Appveyor CI (#422) 2017-02-18 10:37:36 +03:30
jfkthame 44f7d6ecde Guard against underflow when adjusting length (#421) 
* Guard against underflow when adjusting length

With the fuzz-testcase in mozilla bug 1295299, we end up with a recursed lookup that removes 3 items, when `match_positions[idx]` is 0, which results in (unsigned) `end` wrapping to a huge value.

Making `end` a signed int is probably the simplest route to a fix.

Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1295299.

* Add testcase for #421.

Philip Withnall ffde3c9f9e hb-font: Fix a potentially undefined use of memcmp() (#413) 
While it’s fine to call memcmp(x, 0, 0) in practice, the C99 standard
explicitly says that this is not allowed: even if the length is zero,
the pointer arguments must be valid.

The 'avar' table does not allow random access to axis maps,

+hb_ot_var_normalize_variations() and
+hb_ot_var_normalize_coords() instead.
