Security Advisory Description
FreeType commit 1e2eb65048f75c64b68708efed6ce904c31f3b2f was discovered to contain a heap buffer overflow via the function sfnt_init_face.
FreeType 2 before 2017-03-26 has an out-of-bounds write caused by a heap-based buffer overflow related to the t1_builder_close_contour function in psaux/psobjs.c.
FreeType 2 before 2017-03-24 has an out-of-bounds write caused by a heap-based buffer overflow related to the t1_decoder_parse_charstrings function in psaux/t1decode.c.
FreeType 2 before 2017-02-02 has an out-of-bounds write caused by a heap-based buffer overflow related to the tt_size_reset function in truetype/ttobjs.c.
FreeType 2 before 2017-03-07 has an out-of-bounds write related to the TT_Get_MM_Var function in truetype/ttgxvar.c and the sfnt_init_face function in sfnt/sfobjs.c.
FreeType 2 before 2017-03-08 has an out-of-bounds write caused by a heap-based buffer overflow related to the TT_Get_MM_Var function in truetype/ttgxvar.c and the sfnt_init_face function in sfnt/sfobjs.c.
FreeType 2 before 2016-12-16 has an out-of-bounds write caused by a heap-based buffer overflow related to the cff_parser_run function in cff/cffparse.c.
FreeType commit 22a0cccb4d9d002f33c1ba7a4b36812c7d4f46b5 was discovered to contain a segmentation violation via the function FT_Request_Size.
FreeType commit 53dfdcd8198d2b3201a23c4bad9190519ba918db was discovered to contain a segmentation violation via the function FNT_Size_Request.
The parse_charstrings function in type1/t1load.c in FreeType 2 before 2.7 does not ensure that a font contains a glyph name, which allows remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted file.
