Description: 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.
