Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2916-1 advisory.

 It was discovered that Perl incorrectly handled certain regular expressions with an invalid backreference.
 An attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2013-7422)

 Markus Vervier discovered that Perl incorrectly handled nesting in the Data::Dumper module. An attacker could use this issue to cause Perl to consume memory and crash, resulting in a denial of service.
 (CVE-2014-4330)

 Stephane Chazelas discovered that Perl incorrectly handled duplicate environment variables. An attacker could possibly use this issue to bypass the taint protection mechanism. (CVE-2016-2381)

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