Freetype: freetype: denial of service via repeated subroutine allocations in cid font loader

A flaw was found in FreeType, specifically within its CID font loader. A remote attacker could exploit this vulnerability by tricking a user into opening content that embeds or references a specially crafted CID-keyed font. This crafted font can cause repeated allocations and decryptions of subroutine data across multiple font dictionaries, leading to excessive memory and CPU consumption. This can result in a denial of service (DoS) for the application or service processing the font, potentially causing it to hang or terminate.

• Mettez à jour vers 2.13.3+dfsg-1+deb13u1

CVE-2026-23865

An integer overflow in the tt_var_load_item_variation_store function of the Freetype library in versions 2.13.2 and 2.13.3 may allow for an out of bounds read operation when parsing HVAR/VVAR/MVAR tables in OpenType variable fonts. This issue is fixed in version 2.14.2.

• Mettez à jour vers 2.13.3+dfsg-1+deb13u1

CVE-2025-27363

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.

• Mettez à jour vers 2.13.1+dfsg-1

CVE-2022-31782

ftbench.c in FreeType Demo Programs through 2.12.1 has a heap-based buffer overflow.

• Mettez à jour vers 2.6.3-1

CVE-2015-9382

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.

• Mettez à jour vers 2.6.1-0.1

CVE-2015-9381

FreeType before 2.6.1 has a heap-based buffer over-read in T1_Get_Private_Dict in type1/t1parse.c.

• Mettez à jour vers 2.6.1-0.1

CVE-2015-9290

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.

• Mettez à jour vers 2.6.1-0.1

CVE-2018-6942

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.

• Mettez à jour vers 2.9.1-3

CVE-2017-8287

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.

• Mettez à jour vers 2.6.3-3.2

CVE-2017-8105

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.

• Mettez à jour vers 2.6.3-3.2

CVE-2016-10244

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.

• Mettez à jour vers 2.6.3-3.1

CVE-2014-9747

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.

• Mettez à jour vers 2.6-1

CVE-2014-9746

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.

• Mettez à jour vers 2.6-1
