Multiple unspecified vulnerabilities in Opera before 10.54 have unknown impact and attack vectors related to (1) "extremely severe," (2) "highly severe," (3) "moderately severe," and (4) "less severe" issues.

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.
  Workaround :

    There is no known workaround at this time.

The version of Opera installed on the remote host is earlier than 10.54.  Such versions are potentially affected by the following issues :

  - It may be possible to use data URIs in a cross-site     scripting attack. (955)

  - File inputs may disclose the path to selected files.     (960)

  - It may be possible to use certain characters for domain     name spoofing. (961)

  - It may be possible for a widget to use unrestricted file     I/O to execute arbitrary code. (962)

Versions of Opera earlier than 10.54 are potentially affected by multiple vulnerabilities :

  - Opera may be used as a vector for a font issue in the underlying operating system. (KB 954)

  - An extremely severe issue due to an undisclosed error.

  - A highly severe issue due to an undisclosed error.

  - A moderately severe issue due to an undisclosed issue.
