CVE-2026-0943 1 Harfbuzz Project 1 Harfbuzz 2026-01-20 7.5 High
HarfBuzz::Shaper versions before 0.032 for Perl contains a bundled library with a null pointer dereference vulnerability.  Versions before 0.032 contain HarfBuzz 8.4.0 or earlier bundled as hb_src.tar.gz in the source tarball, which is affected by CVE-2026-22693.
CVE-2026-22693 1 Harfbuzz Project 1 Harfbuzz 2026-01-13 5.3 Medium
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 construct an object at the returned pointer address. When hb_malloc fails to allocate memory (which can occur in low-memory conditions or when using custom allocators that simulate allocation failures), it returns NULL. The code then attempts to call the constructor on this null pointer using placement new syntax, resulting in undefined behavior and a Segmentation Fault. This issue has been patched in version 12.3.0.
CVE-2015-8947 2 Harfbuzz Project, Redhat 2 Harfbuzz, Rhel Extras 2025-04-12 N/A
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 3 Google, Harfbuzz Project, Redhat 3 Chrome, Harfbuzz, Rhel Extras 2025-04-12 N/A
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 in hb-ot-font.cc, a different issue than CVE-2015-8947.
CVE-2023-25193 3 Fedoraproject, Harfbuzz Project, Redhat 8 Fedora, Harfbuzz, Enterprise Linux and 5 more 2025-03-25 7.5 High
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 3 Fedoraproject, Harfbuzz Project, Redhat 3 Fedora, Harfbuzz, Enterprise Linux 2024-11-21 5.5 Medium
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 2 Fedoraproject, Harfbuzz Project 2 Fedora, Harfbuzz 2024-11-21 6.5 Medium
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 1 Harfbuzz Project 1 Harfbuzz 2024-11-21 N/A
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.
