CVSS v3.1 |
Heap buffer overflow in Freetype in Google Chrome prior to 86.0.4240.111 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. |
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. |
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 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 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 2017-03-26 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. |
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. |
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. |
Multiple integer overflows in sfnt/ttcmap.c in FreeType before 2.5.4 allow remote attackers to cause a denial of service (out-of-bounds read or memory corruption) or possibly have unspecified other impact via a crafted cmap SFNT table. |
The t42_parse_encoding function in type42/t42parse.c in FreeType before 2.5.4 does not properly update the current position for immediates-only mode, which allows remote attackers to cause a denial of service (infinite loop) via a Type42 font. |
The tt_sbit_decoder_init function in sfnt/ttsbit.c in FreeType before 2.5.4 proceeds with a count-to-size association without restricting the count value, which allows remote attackers to cause a denial of service (integer overflow and out-of-bounds read) or possibly have unspecified other impact via a crafted embedded bitmap. |
The woff_open_font function in sfnt/sfobjs.c in FreeType before 2.5.4 proceeds with offset+length calculations without restricting length values, which allows remote attackers to cause a denial of service (integer overflow and heap-based buffer overflow) or possibly have unspecified other impact via a crafted Web Open Font Format (WOFF) file. |
sfnt/ttload.c in FreeType before 2.5.4 proceeds with offset+length calculations without restricting the values, which allows remote attackers to cause a denial of service (integer overflow and out-of-bounds read) or possibly have unspecified other impact via a crafted SFNT table. |
Multiple integer signedness errors in the pcf_get_encodings function in pcf/pcfread.c in FreeType before 2.5.4 allow remote attackers to cause a denial of service (integer overflow, NULL pointer dereference, and application crash) via a crafted PCF file that specifies negative values for the first column and first row. |
The (1) cf2_initLocalRegionBuffer and (2) cf2_initGlobalRegionBuffer functions in cff/cf2ft.c in FreeType before 2.5.3 do not properly check if a subroutine exists, which allows remote attackers to cause a denial of service (assertion failure), as demonstrated by a crafted ttf file. |
Stack-based buffer overflow in the cf2_hintmap_build function in cff/cf2hints.c in FreeType before 2.5.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large number of stem hints in a font file. |
The tt_cmap4_validate function in sfnt/ttcmap.c in FreeType before 2.5.4 validates a certain length field before that field's value is completely calculated, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted cmap SFNT table. |
FreeType before 2.5.4 does not check for the end of the data during certain parsing actions, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted Type42 font, related to type42/t42parse.c and type1/t1load.c. |
The (1) t1_parse_font_matrix function in type1/t1load.c, (2) cid_parse_font_matrix function in cid/cidload.c, (3) t42_parse_font_matrix function in type42/t42parse.c, and (4) ps_parser_load_field function in psaux/psobjs.c in FreeType before 2.5.4 do not check return values, which allows remote attackers to cause a denial of service (uninitialized memory access and application crash) or possibly have unspecified other impact via a crafted font. |
