Amazon Linux 2 : liblouis (ALAS-2024-2471)

high Nessus Plugin ID 190711


The remote Amazon Linux 2 host is missing a security update.


The version of liblouis installed on the remote host is prior to 2.6.2-21. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2471 advisory.

- Liblouis 3.5.0 has a Segmentation fault in lou_logPrint in logging.c. (CVE-2018-11577)

- Liblouis 3.5.0 has a stack-based Buffer Overflow in the function includeFile in compileTranslationTable.c.

- Liblouis 3.5.0 has a stack-based Buffer Overflow in the function compileHyphenation in compileTranslationTable.c. (CVE-2018-11685)

- Liblouis 3.6.0 has a stack-based Buffer Overflow in the function parseChars in compileTranslationTable.c, a different vulnerability than CVE-2018-11440. (CVE-2018-12085)

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


Run 'yum update liblouis' to update your system.
