CVE-2011-2641 1 Opera 1 Opera Browser 2025-04-11 N/A
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.
CVE-2011-2635 1 Opera 1 Opera Browser 2025-04-11 N/A
The Cascading Style Sheets (CSS) implementation in Opera before 11.10 allows remote attackers to cause a denial of service (application crash) via vectors involving use of the :hover pseudo-class, in conjunction with transforms, for a floated element.
CVE-2011-2637 1 Opera 1 Opera Browser 2025-04-11 N/A
Unspecified vulnerability in Opera before 11.10 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by futura-sciences.com, seoptimise.com, and mitosyfraudes.org.
CVE-2011-3388 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.51 allows remote attackers to cause an insecure site to appear secure or trusted via unspecified actions related to Extended Validation and loading content from trusted sources in an unspecified sequence that causes the address field and page information dialog to contain security information based on the trusted site, instead of the insecure site.
CVE-2011-4686 1 Opera 1 Opera Browser 2025-04-11 N/A
Unspecified vulnerability in the Web Workers implementation in Opera before 11.60 allows remote attackers to cause a denial of service (application crash) via unknown vectors.
CVE-2012-4144 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, does not properly escape characters in DOM elements, which makes it easier for remote attackers to bypass cross-site scripting (XSS) protection mechanisms via a crafted HTML document.
CVE-2008-7297 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera cannot properly restrict modifications to cookies established in HTTPS sessions, which allows man-in-the-middle attackers to overwrite or delete arbitrary cookies via a Set-Cookie header in an HTTP response, related to lack of the HTTP Strict Transport Security (HSTS) includeSubDomains feature, aka a "cookie forcing" issue.
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-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-2010-2661 4 Apple, Microsoft, Opera and 1 more 4 Mac Os X, Windows, Opera Browser and 1 more 2025-04-11 N/A
Opera before 10.54 on Windows and Mac OS X, and before 10.60 on UNIX platforms, does not properly restrict access to the full pathname of a file selected for upload, which allows remote attackers to obtain potentially sensitive information via unspecified DOM manipulations.
CVE-2010-4579 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.00 does not properly constrain dialogs to appear on top of rendered documents, which makes it easier for remote attackers to trick users into interacting with a crafted web site that spoofs the (1) security information dialog or (2) download dialog.
CVE-2011-0682 1 Opera 1 Opera Browser 2025-04-11 N/A
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.
CVE-2011-0685 1 Opera 1 Opera Browser 2025-04-11 N/A
The Delete Private Data feature in Opera before 11.01 does not properly implement the "Clear all email account passwords" option, which might allow physically proximate attackers to access an e-mail account via an unattended workstation.
CVE-2011-4682 1 Opera 1 Opera Browser 2025-04-11 N/A
The JavaScript engine in Opera before 11.60 does not properly implement the in operator, which allows remote attackers to bypass the Same Origin Policy via vectors related to variables on different web sites.
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-2013-1489 6 Google, Microsoft, Mozilla and 3 more 7 Chrome, Internet Explorer, Firefox and 4 more 2025-04-11 N/A
Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 10 and Update 11, when running on Windows using Internet Explorer, Firefox, Opera, and Google Chrome, allows remote attackers to bypass the "Very High" security level of the Java Control Panel and execute unsigned Java code without prompting the user via unknown vectors, aka "Issue 53" and the "Java Security Slider" vulnerability.
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-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.
CVE-2011-2628 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.11 does not properly implement FRAMESET elements, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to page unload.
CVE-2011-3389 9 Canonical, Debian, Google and 6 more 21 Ubuntu Linux, Debian Linux, Chrome and 18 more 2025-04-11 N/A
The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack.
