Opera before 11.62 allows remote attackers to bypass the Same Origin Policy via the (1) history.pushState and (2) history.replaceState functions in conjunction with cross-domain frames, leading to unintended read access to history.state information.

The Opera web browser was updated to 11.62 fixing various bugs and security 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 Windows host is earlier than 11.62 and is, therefore, potentially affected by multiple vulnerabilities :

  - The download dialog box can be displayed in a very     small window thus, tricking a user into not realizing     it is open. Certain keyboard entries after this can     allow a user to take unintended actions. (Issue #1010)

  - The download dialog box can be hidden behind certain     page content thus, tricking a user into not realizing     it is open. Certain user actions after this can allow     a user to take unintended actions. (Issue #1011)

  - Improper restrictions after the use of     'history.pushState' and 'history.replaceState' can     allow information disclosure of state data when cross-     domain frames are in use. (Issue #1012)

  - Dialog boxes can cause the application to display an     incorrect address in the URL bar. (Issue #1013)

  - Certain webpage reloading timing issues can cause the     application to display incorrect information in the URL     bar. (Issue #1014)
