CVSS v3.1 |
| Unspecified vulnerability in Opera before 10.61 allows remote attackers to cause a denial of service (CPU consumption and application hang) via an animated PNG image. |
| 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. |
| The news-feed preview feature in Opera before 10.61 does not properly remove scripts, which allows remote attackers to force subscriptions to arbitrary feeds via crafted content. |
| 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. |
| Opera before 10.60 allows remote attackers to cause a denial of service (application hang) via certain HTML content that has an unclosed SPAN element with absolute positioning. |
| Opera before 10.60 allows remote attackers to cause a denial of service (application hang) via an ended event handler that changes the SRC attribute of an AUDIO element. |
| Opera before 10.60 allows remote attackers to bypass the popup blocker via a javascript: URL and a "fake click." |
| Opera 10.50 allows remote attackers to obtain sensitive information via crafted XSLT constructs, which cause Opera to return cached contents of other pages. |
| 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. |
| Opera before 10.50 on Windows, before 10.52 on Mac OS X, and before 10.60 on UNIX platforms makes widget properties accessible to third-party domains, which allows remote attackers to obtain potentially sensitive information via a crafted web site. |
| 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. |
| 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. |
| 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. |
| Opera 9.52 does not properly handle an IFRAME element with a mailto: URL in its SRC attribute, which allows remote attackers to cause a denial of service (resource consumption) via an HTML document with many IFRAME elements. |
| Opera before 12.13 does not send CORS preflight requests in all required cases, which allows remote attackers to bypass a CSRF protection mechanism via a crafted web site that triggers a CORS request. |
| 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. |
| Heap-based buffer overflow in Opera before 12.11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a long HTTP response. |
| 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. |
| 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. |
| 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. |
