CVE-2011-1337 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.50 allows remote attackers to cause a denial of service (disk consumption) via invalid URLs that trigger creation of error pages.
CVE-2012-4142 4 Apple, Linux, Microsoft and 1 more 4 Mac Os X, Linux Kernel, Windows and 1 more 2025-04-11 N/A
Opera before 12.01 on Windows and UNIX, and before 11.66 and 12.x before 12.01 on Mac OS X, ignores some characters in HTML documents in unspecified circumstances, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document.
CVE-2012-6465 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 12.10 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a malformed SVG image.
CVE-2011-4681 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.60 does not properly consider the number of . (dot) characters that conventionally exist in domain names of different top-level domains, which allows remote attackers to bypass the Same Origin Policy by leveraging access to a different domain name in the same top-level domain, as demonstrated by the .no or .uk domain.
CVE-2011-4685 1 Opera 1 Opera Browser 2025-04-11 N/A
Dragonfly in Opera before 11.60 allows remote attackers to cause a denial of service (application crash) via unspecified content on a web page, as demonstrated by forbes.com.
CVE-2010-5072 1 Opera 1 Opera Browser 2025-04-11 N/A
The JavaScript implementation in Opera 10.5 does not properly restrict the set of values contained in the object returned by the getComputedStyle method, which allows remote attackers to obtain sensitive information about visited web pages by calling this method.
CVE-2010-2455 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera does not properly manage the address bar between the request to open a URL and the retrieval of the new document's content, which might allow remote attackers to conduct spoofing attacks via a crafted HTML document, a related issue to CVE-2010-1206.
CVE-2011-2609 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.50 does not properly restrict data: URIs, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted web site.
CVE-2013-1638 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 12.13 allows remote attackers to execute arbitrary code via crafted clipPaths in an SVG document.
CVE-2010-1728 3 Apple, Microsoft, Opera 3 Mac Os X, Windows, Opera Browser 2025-04-11 N/A
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.
CVE-2012-1926 1 Opera 1 Opera Browser 2025-04-11 N/A
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.
CVE-2012-1928 1 Opera 1 Opera Browser 2025-04-11 N/A
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.
CVE-2010-2576 1 Opera 1 Opera Browser 2025-04-11 N/A
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.
CVE-2012-3559 2 Apple, Opera 2 Mac Os X, Opera Browser 2025-04-11 N/A
Unspecified vulnerability in Opera before 12.00 on Mac OS X has unknown impact and attack vectors, related to a "moderate severity issue."
CVE-2012-3560 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during blocked navigation, which makes it easier for remote attackers to conduct spoofing attacks by detecting and preventing attempts to load a different web page.
CVE-2012-3564 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 12.00 Beta allows remote attackers to cause a denial of service (application hang) via an absolutely positioned wrap=off TEXTAREA element located next to an "overflow: auto" block element.
CVE-2012-3566 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 12.00 Beta allows user-assisted remote attackers to cause a denial of service (application hang) via JavaScript code that changes a form before submission.
CVE-2012-3568 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 12.00 Beta allows remote attackers to cause a denial of service (application crash) via crafted WebGL content, as demonstrated by a codeflow.org WebGL demo.
CVE-2010-2666 3 Apple, Microsoft, Opera 3 Mac Os X, Windows, Opera Browser 2025-04-11 N/A
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.
CVE-2011-0450 2 Microsoft, Opera 2 Windows, Opera Browser 2025-04-11 N/A
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.
