| CVE-2024-56732 | Hig | 0.50 | 8.8 | 0.01 | Dec 27, 2024 | HarfBuzz is a text shaping engine. Starting with 8.5.0 through 10.0.1, there is a heap-based buffer overflow in the hb_cairo_glyphs_from_buffer function. | ||
| CVE-2015-8947 | Hig | 0.43 | 7.6 | 0.02 | Jul 19, 2016 | hb-ot-layout-gpos-table.hh in HarfBuzz before 1.0.5 allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via crafted data, a different vulnerability than CVE-2016-2052. | ||
| CVE-2016-2052 | Hig | 0.42 | 7.6 | 0.01 | Jan 25, 2016 | Multiple unspecified vulnerabilities in HarfBuzz before 1.0.6, as used in Google Chrome before 48.0.2564.82, allow attackers to cause a denial of service or possibly have other impact via crafted data, as demonstrated by a buffer over-read resulting from an inverted length check… | ||
| CVE-2011-3193 | 0.01 | — | 0.08 | Jun 16, 2012 | Heap-based buffer overflow in the Lookup_MarkMarkPos function in the HarfBuzz module (harfbuzz-gpos.c), as used by Qt before 4.7.4 and Pango, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted font file. | |||
| CVE-2026-22693 | 0.00 | — | 0.00 | Jan 10, 2026 | HarfBuzz is a text shaping engine. Prior to version 12.3.0, a null pointer dereference vulnerability exists in the SubtableUnicodesCache::create function located in src/hb-ot-cmap-table.hh. The function fails to check if hb_malloc returns NULL before using placement new to… | |||
| CVE-2023-25193 | 0.00 | — | 0.02 | Feb 4, 2023 | hb-ot-layout-gsubgpos.hh in HarfBuzz through 6.0.0 allows attackers to trigger O(n^2) growth via consecutive marks during the process of looking back for base glyphs when attaching marks. | |||
| CVE-2022-33068 | 0.00 | — | 0.01 | Jun 22, 2022 | An integer overflow in the component hb-ot-shape-fallback.cc of Harfbuzz v4.3.0 allows attackers to cause a Denial of Service (DoS) via unspecified vectors. | |||
| CVE-2021-45931 | 0.00 | — | 0.02 | Dec 31, 2021 | HarfBuzz 2.9.0 has an out-of-bounds write in hb_bit_set_invertible_t::set (called from hb_sparseset_t<hb_bit_set_invertible_t>::set and hb_set_copy). | |||
| CVE-2015-9274 | 0.00 | — | 0.02 | Nov 15, 2018 | HarfBuzz before 1.0.4 allows remote attackers to cause a denial of service (invalid read of two bytes and application crash) because of GPOS and GSUB table mishandling, related to hb-ot-layout-gpos-table.hh, hb-ot-layout-gsub-table.hh, and hb-ot-layout-gsubgpos-private.hh. | |||
| CVE-2011-0064 | 0.00 | — | 0.03 | Mar 7, 2011 | The hb_buffer_ensure function in hb-buffer.c in HarfBuzz, as used in Pango 1.28.3, Firefox, and other products, does not verify that memory reallocations succeed, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or… |
