Description

According to the version of the liblouis packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  • A missing fix for one stack-based buffer overflow in findTable() for CVE-2014-8184 was discovered. An attacker could cause denial of service or potentially allow arbitrary code execution. (CVE-2017-15101)

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.
