Hi

Please unblock package freetype

The update fixes CVE-2016-10244, tracked as #856971.

The parse_charstrings function in does not ensure that a font contains
a glyph name, which allows remote attackers to cause a denial of
service via a crafted file.

Does not warrant a DSA for stable, but would be nice to have it
already fixed for stretch.

Needs a d-i 'ack' if accepted.

unblock freetype/2.6.3-3.1

Attached debdiff against the version in stretch.

Regards,
Salvatore
