CVE ID | Published | Description | Score | Severity |
---|---|---|---|---|
An out of bounds write exists in FreeType versions 2.13.0 and below (newer versions of FreeType are not vulnerable) when attempting to parse font subglyph structures related to TrueType GX and variable font files. The vulnerable code assigns a signed short value to an unsigned long and then adds a static value causing it to wrap around and allocate too small of a heap buffer. The code then writes up to 6 signed long integers out of bounds relative to this buffer. This may result in arbitrary code execution. This vulnerability may have been exploited in the wild. | 8.1 |

FreeType commit 1e2eb65048f75c64b68708efed6ce904c31f3b2f was discovered to contain a heap buffer overflow via the function sfnt_init_face. | 9.8 |

FreeType commit 53dfdcd8198d2b3201a23c4bad9190519ba918db was discovered to contain a segmentation violation via the function FNT_Size_Request. | 7.5 |

FreeType commit 22a0cccb4d9d002f33c1ba7a4b36812c7d4f46b5 was discovered to contain a segmentation violation via the function FT_Request_Size. | 7.5 |
High |
||
FreeType before 2.6.2 has a heap-based buffer over-read in tt_cmap14_validate in sfnt/ttcmap.c. | 6.5 |
Medium |
||
FreeType before 2.6.1 has a buffer over-read in skip_comment in psaux/psobjs.c because ps_parser_skip_PS_token is mishandled in an FT_New_Memory_Face operation. | 6.5 |
Medium |
||
FreeType before 2.6.1 has a heap-based buffer over-read in T1_Get_Private_Dict in type1/t1parse.c. | 8.8 |
High |
||
In FreeType before 2.6.1, a buffer over-read occurs in type1/t1parse.c on function T1_Get_Private_Dict where there is no check that the new values of cur and limit are sensible before going to Again. | 9.8 |
Critical |
||
An issue was discovered in FreeType 2 through 2.9. A NULL pointer dereference in the Ins_GETVARIATION() function within ttinterp.c could lead to DoS via a crafted font file. | 6.5 |
Medium |
||
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. | 9.8 |
Critical |
||
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. | 9.8 |
Critical |
||
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. | 9.8 |
Critical |
||
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. | 9.8 |
Critical |
||
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. | 9.8 |
Critical |
||
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. | 7.8 |
