The remote host is affected by the vulnerability described in GLSA-201206-03 (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, possibly resulting in execution of arbitrary code with the       privileges of the process or a Denial of Service condition. A remote       attacker may be able to: trick users into downloading and executing       arbitrary files, bypass intended access restrictions, spoof trusted       content, spoof URLs, bypass the Same Origin Policy, obtain sensitive       information, force subscriptions to arbitrary feeds, bypass the popup       blocker, bypass CSS filtering, conduct cross-site scripting attacks, or       have other unknown impact.
    A local attacker could perform symlink attacks to overwrite arbitrary       files with the privileges of the user running the application or possibly       obtain sensitive information.
    A physically proximate attacker may be able to access an email account.
