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.

This update for liblouis, python-luis and python3-louis fixes the following issue :

Security issue fixed :

CVE-2018-17294: Fixed an out of bounds read in matchCurrentInput function which could allow a remote attacker to cause Denail of Service (bsc#1109319).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
