Opera before 12.01 on Windows and UNIX, and before 11.66 and 12.x before 12.01 on Mac OS X, allows user-assisted remote attackers to trick users into downloading and executing arbitrary files via a small window for the download dialog, a different vulnerability than CVE-2012-1924.

Opera before 11.62 allows remote attackers to spoof the address field by triggering the launch of a dialog window associated with a different domain.

Opera before 11.62 allows remote attackers to spoof the address field by triggering a page reload followed by a redirect to a different domain.

Opera before 11.62 on Mac OS X allows remote attackers to spoof the address field and security dialogs via crafted styling that causes page content to be displayed outside of the intended content area.

Opera 11.11 allows remote attackers to cause a denial of service (application crash) by setting the FACE attribute of a FONT element within an IFRAME element after changing the SRC attribute of this IFRAME element to an about:blank value.

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.

Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors related to selecting a text node, and closed pop-up windows, removed pop-up windows, and IFRAME elements.

Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via a SELECT element that contains many OPTION elements.

Opera before 11.50 allows remote attackers to cause a denial of service (application crash) by using "injected script" to set the SRC attribute of an IFRAME element.

Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (memory consumption) via unknown content on a web page, as demonstrated by test262.ecmascript.org.

Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by progorod.ru.

Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via web script that moves a (1) AUDIO element or (2) VIDEO element between windows.

Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via a gradient with many stops, related to the implementation of CANVAS elements, SVG, and Cascading Style Sheets (CSS).

The Array.prototype.join method in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via a non-array object that contains initial holes.

Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors involving SVG animation.

Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors related to form layout.

The SVG implementation in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors involving a path on which many characters are drawn.

Unspecified vulnerability in the DOM implementation in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by live.com.

Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application hang) via unknown content on a web page, as demonstrated by domiteca.com.

Unspecified vulnerability in the Web Workers implementation in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via unknown vectors.

Opera before 11.67 and 12.x before 12.02 allows remote attackers to cause truncation of a dialog, and possibly trigger downloading and execution of arbitrary programs, via a crafted web site.

Opera before 12.10 does not properly implement the Cross-Origin Resource Sharing (CORS) specification, which allows remote attackers to bypass intended page-content restrictions via a crafted request.
