Opera before 9.27 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted scaled image pattern in an HTML CANVAS element, which triggers memory corruption.

Multiple buffer overflows in Opera before 9.63 might allow (1) remote attackers to execute arbitrary code via a crafted text area, or allow (2) user-assisted remote attackers to execute arbitrary code via a long host name in a file: URL. NOTE: this might overlap CVE-2008-5178.

Opera before 10.53 on Windows and Mac OS X does not properly handle a series of document modifications that occur asynchronously, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via JavaScript that writes <marquee> sequences in an infinite loop, leading to attempted use of uninitialized memory. NOTE: this might overlap CVE-2006-6955.

Integer truncation error in opera.dll in Opera before 11.01 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via an HTML form with a select element that contains a large number of children.

Heap-based buffer overflow in Opera before 10.61 allows remote attackers to execute arbitrary code or cause a denial of service (application crash or hang) via vectors related to HTML5 canvas painting operations that occur during the application of transformations.

Opera before 10.54 on Windows and Mac OS X does not properly enforce permission requirements for widget filesystem access and directory selection, which allows user-assisted remote attackers to create or modify arbitrary files, and consequently execute arbitrary code, via widget File I/O operations.

Opera before 10.63 does not properly restrict web script in unspecified circumstances involving reloads and redirects, which allows remote attackers to spoof the Address Bar, conduct cross-site scripting (XSS) attacks, and possibly execute arbitrary code by leveraging the ability of a script to interact with a web page from (1) a different domain or (2) a different security context.

Opera before 9.64 allows remote attackers to execute arbitrary code via a crafted JPEG image that triggers memory corruption.

The Javascript SVG support in Opera before 9.10 does not properly validate object types in a createSVGTransformFromMatrix request, which allows remote attackers to execute arbitrary code via JavaScript code that uses an invalid object in this request that causes a controlled pointer to be referenced during the virtual function call.

Unspecified vulnerability in Opera before 9.24, when using an "external" newsgroup or e-mail client, allows remote attackers to execute arbitrary commands via unknown vectors.

Heap-based buffer overflow in Opera before 12.11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a long HTTP response.

Opera before 12.10 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a malformed SVG image.

Opera before 11.65 does not properly restrict the opening of a pop-up window in response to the first click of a double-click action, which makes it easier for user-assisted remote attackers to conduct cross-site scripting (XSS) attacks or execute arbitrary code via a crafted web site.

Opera before 11.00 on Windows does not properly implement the Insecure Third Party Module warning message, which might make it easier for user-assisted remote attackers to have an unspecified impact via a crafted module.

Opera before 9.51 does not properly manage memory within functions supporting the CANVAS element, which allows remote attackers to read uninitialized memory contents by using JavaScript to read a canvas image.

Opera before 9.25 allows remote attackers to obtain potentially sensitive memory contents via a crafted bitmap (BMP) file, as demonstrated using a CANVAS element and JavaScript in an HTML document for copying these contents from 9.50 beta, a related issue to CVE-2008-0420.

Algorithmic complexity vulnerability in Opera 9.50 beta and 9.x before 9.25 allows remote attackers to cause a denial of service (CPU consumption) via a crafted bitmap (BMP) file that triggers a large number of calculations and checks.

Unspecified vulnerability in Opera before 9.63 allows remote attackers to "reveal random data" via unknown vectors.

The downloads manager in Opera before 11.01 on Windows does not properly determine the pathname of the filesystem-viewing application, which allows user-assisted remote attackers to execute arbitrary code via a crafted web site that hosts an executable file.

Opera before 11.65 does not ensure that keyboard sequences are associated with a visible window, which makes it easier for user-assisted remote attackers to conduct cross-site scripting (XSS) attacks or execute arbitrary code via a crafted web site, related to a "hidden keyboard navigation" issue.

Unspecified vulnerability in Opera before 9.24 allows remote attackers to overwrite functions on pages from other domains and bypass the same-origin policy via unknown vectors.

Adobe Macromedia Flash Player 7 and 9, when used with Opera before 9.20 or Konqueror before 20070613, allows remote attackers to obtain sensitive information (browser keystrokes), which are leaked to the Flash Player applet.

Opera before 10.61 does not properly suppress clicks on download dialogs that became visible after a recent tab change, which allows remote attackers to conduct clickjacking attacks, and consequently execute arbitrary code, via vectors involving (1) closing a tab or (2) hiding a tab, a related issue to CVE-2005-2407.
