The remote host is affected by the vulnerability described in GLSA-201406-14 (Opera: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Opera. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted web       page using Opera, possibly resulting in execution of arbitrary code with       the privileges of the process or a Denial of Service condition.
      Furthermore, a remote attacker may be able to obtain sensitive       information, conduct Cross-Site Scripting (XSS) attacks, or bypass       security restrictions.
    A local attacker may be able to obtain sensitive information.
  Workaround :
