Synopsis

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

Description

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 ALAS2-2023-1941 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.
(CVE-2018-11684)

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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update liblouis' to update your system.
