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-2011-2630 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
Opera before 11.11 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 occurring after the opening of a popup of the Easy Sticky Note extension.
CVE-2010-2659 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 10.50 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.
CVE-2010-1728 3 Apple, Microsoft, Opera 3 Mac Os X, Windows, Opera Browser 2023-12-10 9.3 HIGH N/A
Opera before 10.53 on Windows and Mac OS X does not properly handle a series of document modifications that occur asynchronously, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via JavaScript that writes <marquee> sequences in an infinite loop, leading to attempted use of uninitialized memory. NOTE: this might overlap CVE-2006-6955.
CVE-2011-2615 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application hang) via unknown content on a web page, as demonstrated by domiteca.com.
CVE-2011-0682 1 Opera 1 Opera Browser 2023-12-10 9.3 HIGH 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-2010-4047 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
Opera before 10.63 does not properly select the security context of JavaScript code associated with an error page, which allows user-assisted remote attackers to conduct cross-site scripting (XSS) attacks via a crafted web site.
CVE-2010-2664 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
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.

CVE-2011-3389 9 Canonical, Debian, Google and 6 more 17 Ubuntu Linux, Debian Linux, Chrome and 14 more 2023-12-10 4.3 MEDIUM 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-2010-2455 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
