CVE-2010-4582 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.00 does not properly handle security policies during updates to extensions, which might allow remote attackers to bypass intended access restrictions via unspecified vectors.
CVE-2010-4583 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.00, when Opera Turbo is enabled, does not display a page's security indication, which makes it easier for remote attackers to spoof trusted content via a crafted web site.
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-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-2011-3389 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.
CVE-2010-2421 1 Opera 1 Opera Browser 2025-04-11 N/A
Multiple unspecified vulnerabilities in Opera before 10.54 have unknown impact and attack vectors related to (1) "extremely severe," (2) "highly severe," (3) "moderately severe," and (4) "less severe" issues.
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-2011-0683 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.01 does not properly restrict the use of opera: URLs, which makes it easier for remote attackers to conduct clickjacking attacks via a crafted web site.
CVE-2011-0684 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.01 does not properly handle redirections and unspecified other HTTP responses, which allows remote web servers to obtain sufficient access to local files to use these files as page resources, and consequently obtain potentially sensitive information from the contents of the files, via an unknown response manipulation.
CVE-2012-1003 1 Opera 1 Opera Browser 2025-04-11 N/A
Multiple integer overflows in Opera 11.60 and earlier allow remote attackers to cause a denial of service (application crash) via a large integer argument to the (1) Int32Array, (2) Float32Array, (3) Float64Array, (4) Uint32Array, (5) Int16Array, or (6) ArrayBuffer function. NOTE: the vendor reportedly characterizes this as "a stability issue, not a security issue."
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-2011-4690 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera 11.60 and earlier does not prevent capture of data about the times of Same Origin Policy violations during IFRAME loading attempts, which makes it easier for remote attackers to determine whether a document exists in the browser cache via crafted JavaScript code.
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-2010-5068 1 Opera 1 Opera Browser 2025-04-11 N/A
The Cascading Style Sheets (CSS) implementation in Opera 10.5 does not properly handle the :visited pseudo-class, which allows remote attackers to obtain sensitive information about visited web pages via a crafted HTML document, a related issue to CVE-2010-2264.
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-2012-3555 1 Opera 1 Opera Browser 2025-04-11 N/A
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.
CVE-2012-3556 1 Opera 1 Opera Browser 2025-04-11 N/A
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.
CVE-2012-3562 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 crash) via a crafted web page that is not properly handled during a reload, as demonstrated by a "multiple origin camera test" page.
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.
