The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3213-1 advisory.

Stefan Esser discovered that the GD library incorrectly handled memory when processing certain images. If     a user or automated system were tricked into processing a specially crafted image, an attacker could cause     a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS, Ubuntu     16.04 LTS and Ubuntu 16.10. (CVE-2016-10166)

It was discovered that the GD library incorrectly handled certain malformed images. If a user or automated     system were tricked into processing a specially crafted image, an attacker could cause a denial of     service. (CVE-2016-10167)

It was discovered that the GD library incorrectly handled certain malformed images. If a user or automated     system were tricked into processing a specially crafted image, an attacker could cause a denial of     service, or possibly execute arbitrary code. (CVE-2016-10168)

Ibrahim El-Sayed discovered that the GD library incorrectly handled certain malformed TGA images. If a     user or automated system were tricked into processing a specially crafted TGA image, an attacker could     cause a denial of service. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10.
(CVE-2016-6906)

Ibrahim El-Sayed discovered that the GD library incorrectly handled certain malformed WebP images. If a     user or automated system were tricked into processing a specially crafted WebP image, an attacker could     cause a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS,     Ubuntu 16.04 LTS and Ubuntu 16.10. (CVE-2016-6912)

It was discovered that the GD library incorrectly handled creating oversized images. If a user or     automated system were tricked into creating a specially crafted image, an attacker could cause a denial of     service. (CVE-2016-9317)

It was discovered that the GD library incorrectly handled filling certain images. If a user or automated     system were tricked into filling an image, an attacker could cause a denial of service. (CVE-2016-9933)

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.
