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
