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.
CVE-2011-2628 1 Opera 1 Opera Browser 2025-04-11 10.0 HIGH N/A
Opera before 11.11 does not properly implement FRAMESET elements, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to page unload.
CVE-2010-3019 1 Opera 1 Opera Browser 2025-04-11 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-2011-4686 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Unspecified vulnerability in the Web Workers implementation in Opera before 11.60 allows remote attackers to cause a denial of service (application crash) via unknown vectors.

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.
CVE-2012-6461 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
The X.509 certificate-validation functionality in the https implementation in Opera before 12.10 allows remote attackers to trigger a false indication of successful revocation-status checking by causing a failure of a single checking service.
CVE-2010-1989 1 Opera 1 Opera Browser 2025-04-11 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-2012-4144 4 Apple, Linux, Microsoft and 1 more 4 Mac Os X, Linux Kernel, Windows and 1 more 2025-04-11 4.3 MEDIUM N/A
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.
CVE-2012-3560 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during blocked navigation, which makes it easier for remote attackers to conduct spoofing attacks by detecting and preventing attempts to load a different web page.
CVE-2010-5068 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
The Cascading Style Sheets (CSS) implementation in Opera 10.5 does not properly handle the :visited pseudo-class, which allows remote attackers to obtain sensitive information about visited web pages via a crafted HTML document, a related issue to CVE-2010-2264.
CVE-2010-4581 1 Opera 1 Opera Browser 2025-04-11 10.0 HIGH N/A
Unspecified vulnerability in Opera before 11.00 has unknown impact and attack vectors, related to "a high severity issue."

Opera before 11.65 does not properly restrict the opening of a pop-up window in response to the first click of a double-click action, which makes it easier for user-assisted remote attackers to conduct cross-site scripting (XSS) attacks or execute arbitrary code via a crafted web site.
CVE-2011-0686 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Unspecified vulnerability in Opera before 11.01 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by vkontakte.ru.
CVE-2012-6465 1 Opera 1 Opera Browser 2025-04-11 9.3 HIGH N/A
Opera before 12.10 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a malformed SVG image.
CVE-2012-3561 1 Opera 1 Opera Browser 2025-04-11 10.0 HIGH 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-2011-2623 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Unspecified vulnerability in the SVG BiDi implementation in Opera before 11.50 allows remote attackers to cause a denial of service (application crash or hang) via unknown vectors.
