CVE-2010-4579 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM 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-2010-4582 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM 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-2011-0684 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM 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-2011-2637 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM 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-2011-4683 1 Opera 1 Opera Browser 2023-12-10 10.0 HIGH N/A
Unspecified vulnerability in Opera before 11.60 has unknown impact and attack vectors, related to a "moderately severe issue."
CVE-2010-3019 1 Opera 1 Opera Browser 2023-12-10 9.3 HIGH N/A
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.
CVE-2011-1824 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
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-2010-1989 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
Opera 9.52 executes a mail application in situations where an IMG element has a SRC attribute that is a redirect to a mailto: URL, which allows remote attackers to cause a denial of service (excessive application launches) via an HTML document with many images, a related issue to CVE-2010-0181.
CVE-2010-1349 2 Microsoft, Opera 2 Windows, Opera Browser 2023-12-10 10.0 HIGH N/A
Integer overflow in Opera 10.10 through 10.50 allows remote attackers to execute arbitrary code via a large Content-Length value, which triggers a heap overflow.
CVE-2011-0450 2 Microsoft, Opera 2 Windows, Opera Browser 2023-12-10 7.6 HIGH 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-2010-4050 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
Opera before 10.63 allows remote attackers to cause a denial of service (memory corruption) by referencing an SVG document in an IMG element.
CVE-2010-4043 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
Opera before 10.63 does not prevent interpretation of a cross-origin document as a CSS stylesheet when the document lacks a CSS token sequence, which allows remote attackers to obtain sensitive information via a crafted document.
CVE-2010-4049 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
Opera before 10.63 allows remote attackers to cause a denial of service (application crash) via a Flash movie with a transparent Window Mode (aka wmode) property, which is not properly handled during navigation away from the containing HTML document.
CVE-2011-2625 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via a SELECT element that contains many OPTION elements.
CVE-2011-2614 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
The SVG implementation in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors involving a path on which many characters are drawn.
CVE-2010-2660 4 Apple, Microsoft, Opera and 1 more 4 Mac Os X, Windows, Opera Browser and 1 more 2023-12-10 4.3 MEDIUM N/A
Opera before 10.54 on Windows and Mac OS X, and before 10.60 on UNIX platforms, does not properly restrict certain uses of homograph characters in domain names, which makes it easier for remote attackers to spoof IDN domains via unspecified choices of characters.
CVE-2010-2421 1 Opera 1 Opera Browser 2023-12-10 10.0 HIGH 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-2011-1337 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM 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-2011-2611 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
Unspecified vulnerability in the printing functionality in Opera before 11.50 allows user-assisted remote attackers to cause a denial of service (application crash) via a crafted web page.
CVE-2008-7297 1 Opera 1 Opera Browser 2023-12-10 5.8 MEDIUM 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.
