"This update for freetype2 fixes the following security issues :

  - CVE-2016-10244: Make sure that the parse_charstrings
    function in type1/t1load.c does ensure that a font
    contains a glyph name to prevent a DoS through a
    heap-based buffer over-read or possibly have unspecified
    other impact via a crafted file (bsc#1028103)

  - CVE-2017-8105: Fix an out-of-bounds write caused by a
    heap-based buffer overflow related to the
    t1_decoder_parse_charstrings function in
    psaux/t1decode.ca (bsc#1035807)

  - CVE-2017-8287: an out-of-bounds write caused by a
    heap-based buffer overflow related to the
    t1_builder_close_contour function in psaux/psobjs.c
    (bsc#1036457)

  - Fix several integer overflow issues in
    truetype/ttinterp.c (bsc#1079600)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
