According to the versions of the liblouis packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
Liblouis 3.5.0 has a stack-based Buffer Overflow in the function parseChars in compileTranslationTable.c.(CVE-2018-11440)
Liblouis 3.5.0 has a stack-based Buffer Overflow in the function parseChars in compileTranslationTable.c, a different vulnerability than CVE-2018-11440.(CVE-2018-11683)
Liblouis 3.5.0 has a stack-based Buffer Overflow in the function includeFile in compileTranslationTable.c.(CVE-2018-11684)
Liblouis 3.5.0 has a stack-based Buffer Overflow in the function compileHyphenation in compileTranslationTable.c.(CVE-2018-11685)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
