"An update for liblouis is now available for Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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) :

* A missing fix for one stack-based buffer overflow in findTable() for
CVE-2014-8184 was discovered. An attacker could cause denial of
service or potentially allow arbitrary code execution.
(CVE-2017-15101)

Red Hat would like to thank Samuel Thibault for reporting this issue.

Note that Tenable Network Security has attempted to extract the
preceding description block directly from the corresponding Red Hat
security advisory. Virtuozzo provides no description for VZLSA
advisories. Tenable has attempted to automatically clean and format
it as much as possible without introducing additional issues.");
