Synopsis

The remote Red Hat host is missing one or more security updates for liblouis.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:3111 advisory.

Liblouis is an open source braille translator and back-translator named in honor of Louis Braille. It features support for computer and literary braille, supports contracted and uncontracted translation for many languages and has support for hyphenation. New languages can easily be added through tables that support a rule or dictionary based approach. Liblouis also supports math braille (Nemeth and Marburg).

Security Fix(es):

* Multiple flaws were found in the processing of translation tables in liblouis. An attacker could crash or potentially execute arbitrary code using malicious translation tables. (CVE-2014-8184, CVE-2017-13738, CVE-2017-13740, CVE-2017-13741, CVE-2017-13742, CVE-2017-13743, CVE-2017-13744)

The CVE-2014-8184 issue was discovered by Raphael Sanchez Prudencio (Red Hat).

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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

Update the RHEL liblouis package based on the guidance in RHSA-2017:3111.
