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

high Nessus Plugin ID 173180

Language:

Synopsis

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

Description

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

 - 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-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.
 (CVE-2023-25193)

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

Solution

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