The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3134-1 advisory.
It was discovered that the smtplib library in Python did not return an error when StartTLS fails. A remote attacker could possibly use this to expose sensitive information. (CVE-2016-0772)
Rmi Rampin discovered that Python would not protect CGI applications from contents of the HTTP_PROXY environment variable when based on the contents of the Proxy header from HTTP requests. A remote attacker could possibly use this to cause a CGI application to redirect outgoing HTTP requests. (CVE-2016-1000110)
Insu Yun discovered an integer overflow in the zipimporter module in Python that could lead to a heap- based overflow. An attacker could use this to craft a special zip file that when read by Python could possibly execute arbitrary code. (CVE-2016-5636)
Guido Vranken discovered that the urllib modules in Python did not properly handle carriage return line feed (CRLF) in headers. A remote attacker could use this to craft URLs that inject arbitrary HTTP headers.
This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2016-5699)
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.
