CVSS v3.1 |
| Opera before 11.50 allows remote attackers to cause a denial of service (application crash) by using "injected script" to set the SRC attribute of an IFRAME element. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| Opera before 11.60 allows remote attackers to spoof the address bar via unspecified homograph characters, a different vulnerability than CVE-2010-2660. |
| Opera before 12.01 on Windows and UNIX, and before 11.66 and 12.x before 12.01 on Mac OS X, ignores some characters in HTML documents in unspecified circumstances, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document. |
| Opera before 12.01 allows remote attackers to cause a denial of service (application crash) via a crafted web site, as demonstrated by the Lenovo "Shop now" page. |
| Opera before 11.50 allows remote attackers to cause a denial of service (disk consumption) via invalid URLs that trigger creation of error pages. |
| Opera before 12.10 does not properly implement the Cross-Origin Resource Sharing (CORS) specification, which allows remote attackers to bypass intended page-content restrictions via a crafted request. |
| Opera before 12.10 follows Internet shortcuts that are referenced by a (1) IMG element or (2) other inline element, which makes it easier for remote attackers to conduct phishing attacks via a crafted web site, as exploited in the wild in November 2012. |
| Opera before 12.12 allows remote attackers to spoof the address field via a high rate of HTTP requests. |
| Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors related to selecting a text node, and closed pop-up windows, removed pop-up windows, and IFRAME elements. |
| Opera before 12.12 does not properly allocate memory for GIF images, which allows remote attackers to execute arbitrary code or cause a denial of service (memory overwrite) via a malformed image. |
| Unspecified vulnerability in Opera before 12.15 has unknown impact and attack vectors, related to a "moderately severe issue." |
| 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 11.60 does not properly consider the number of . (dot) characters that conventionally exist in domain names of different top-level domains, which allows remote attackers to bypass the Same Origin Policy by leveraging access to a different domain name in the same top-level domain, as demonstrated by the .no or .uk domain. |
| 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. |
| 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." |
