Amazon Linux 2023 : harfbuzz, harfbuzz-devel, harfbuzz-icu (ALAS2023-2023-111)

high Nessus Plugin ID 173180


The remote Amazon Linux 2023 host is missing a security update.


It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-111 advisory.

- An integer overflow in the component of Harfbuzz v4.3.0 allows attackers to cause a Denial of Service (DoS) via unspecified vectors. (CVE-2022-33068)

- 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.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Run 'dnf update harfbuzz --releasever=2023.0.20230222 ' to update your system.
