CVE-2018-17294 (opens in a new tab)How to fix?
Upgrade Debian:12 liblouis to version 3.7.0-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream liblouis package and not the liblouis package as distributed by Debian.
See How to fix? for Debian:12 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.
