This update for freetype2 fixes the following issues: Security issue fixed :

  • CVE-2016-10244: The parse_charstrings function in type1/t1load.c did not ensure that a font contains a glyph name, which allowed remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted file (bsc#1028103).

  • CVE-2017-8105: Fixed 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)

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.
