There is no fixed version for RHEL:8 liblouis.
NVD Description
Note: Versions mentioned in the description apply only to the upstream liblouis package and not the liblouis package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
The matchCurrentInput function inside lou_translateString.c of Liblouis prior to 3.7 does not check the input string's length, allowing attackers to cause a denial of service (application crash via out-of-bounds read) by crafting an input file with certain translation dictionaries.
