Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3498-1 advisory.

 Alex Nichols discovered that curl incorrectly handled NTLM authentication credentials. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS, Ubuntu 17.04 and Ubuntu 17.10. (CVE-2017-8816)

 It was discovered that curl incorrectly handled FTP wildcard matching. A remote attacker could use this issue to cause curl to crash, resulting in a denial of service, or possibly obtain sensitive information.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
