The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3408-1 advisory.
It was discovered that an illegal address access can be made in Liblouis. A remote attacker can take advantange of this to access sensitive information. (CVE-2017-13738, CVE-2017-13744)
It was discovered a heap-based buffer overflow that causes bytes out-of-bounds write in Liblouis. A remote attacker can use this to denial of service or remote code execution. (CVE-2017-13739)
It was discovered a stack-based buffer overflow in Liblouis. A remote attacker can use this to denial of service or possibly unspecified other impact. (CVE-2017-13740, CVE-2017-13742)
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
