CVE-2011-2631 1 Opera 1 Opera Browser 2025-04-11 N/A
The Cascading Style Sheets (CSS) implementation in Opera before 11.11 does not properly handle the column-count property, which allows remote attackers to cause a denial of service (infinite repaint loop and application hang) via a web page, as demonstrated by an unspecified Wikipedia page.
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-2011-2641 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-2012-1251 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 9.63 does not properly verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
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-2012-1929 2 Apple, Opera 2 Mac Os X, Opera Browser 2025-04-11 N/A
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.
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-2011-0682 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-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-2010-4585 1 Opera 1 Opera Browser 2025-04-11 N/A
Unspecified vulnerability in the auto-update functionality in Opera before 11.00 allows remote attackers to cause a denial of service (application crash) by triggering an Opera Unite update.
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-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-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-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-2012-3561 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.64 does not properly allocate memory for URL strings, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted string.
CVE-2010-4586 1 Opera 1 Opera Browser 2025-04-11 N/A
The default configuration of Opera before 11.00 enables WebSockets functionality, which has unspecified impact and remote attack vectors, possibly a related issue to CVE-2010-4508.
CVE-2010-4587 2 Microsoft, Opera 2 Windows, Opera Browser 2025-04-11 N/A
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.
CVE-2011-0681 1 Opera 1 Opera Browser 2025-04-11 N/A
The Cascading Style Sheets (CSS) Extensions for XML implementation in Opera before 11.01 recognizes links to javascript: URLs in the -o-link property, which makes it easier for remote attackers to bypass CSS filtering via a crafted URL.

The VEGAOpBitmap::AddLine function in Opera before 10.61 does not properly initialize memory during processing of the SIZE attribute of a SELECT element, which allows remote attackers to trigger an invalid memory write operation, and consequently cause a denial of service (application crash) or possibly execute arbitrary code, via a large integer attribute value.
CVE-2011-2610 1 Opera 1 Opera Browser 2025-04-11 N/A
Unspecified vulnerability in Opera before 11.50 has unknown impact and attack vectors, related to a "moderately severe issue."
