An update for harfbuzz is now available for openEuler-24.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2026-1149 Final 1.0 1.0 2026-01-16 Initial 2026-01-16 2026-01-16 openEuler SA Tool V1.0 2026-01-16 harfbuzz security update An update for harfbuzz is now available for openEuler-24.03-LTS-SP1 HarfBuzz is a text-shaping engine. If you give HarfBuzz a font and a string containing a sequence of Unicode codepoints, HarfBuzz selects and positions the corresponding glyphs from the font, applying all of the necessary layout rules and font features. HarfBuzz then returns the string to you in the form that is correctly arranged for the language and writing system. Security Fix(es): 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-2026-22693) An update for harfbuzz is now available for openEuler-24.03-LTS-SP1. openEuler Security has rated this update as having a security impact of medium.
