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.
