CVE-2012-3561 1 Opera 1 Opera Browser 2025-04-11 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-2012-4144 4 Apple, Linux, Microsoft and 1 more 4 Mac Os X, Linux Kernel, Windows and 1 more 2025-04-11 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-2011-4687 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.60 allows remote attackers to cause a denial of service (CPU and memory consumption) via unspecified content on a web page, as demonstrated by a page under the cisco.com home page.
CVE-2014-1870 2 Apple, Opera 2 Mac Os X, Opera Browser 2025-04-11 N/A
Opera before 19 on Mac OS X allows user-assisted remote attackers to spoof the address bar via vectors involving a drag-and-drop operation.
CVE-2010-4581 1 Opera 1 Opera Browser 2025-04-11 N/A
Unspecified vulnerability in Opera before 11.00 has unknown impact and attack vectors, related to "a high severity issue."
CVE-2010-5068 1 Opera 1 Opera Browser 2025-04-11 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-2011-0687 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.01 does not properly implement Wireless Application Protocol (WAP) dropdown lists, which allows user-assisted remote attackers to cause a denial of service (application crash) via a crafted WAP document.
CVE-2012-1924 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.62 allows user-assisted remote attackers to trick users into downloading and executing arbitrary files via a small window for the download dialog.
CVE-2012-1925 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.62 does not ensure that a dialog window is placed on top of content windows, which makes it easier for user-assisted remote attackers to trick users into downloading and executing arbitrary files via a download dialog located under other windows.
CVE-2010-2662 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 10.60 allows remote attackers to bypass the popup blocker via a javascript: URL and a "fake click."
CVE-2010-2664 1 Opera 1 Opera Browser 2025-04-11 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-2011-4683 1 Opera 1 Opera Browser 2025-04-11 N/A
Unspecified vulnerability in Opera before 11.60 has unknown impact and attack vectors, related to a "moderately severe issue."
CVE-2010-1728 3 Apple, Microsoft, Opera 3 Mac Os X, Windows, Opera Browser 2025-04-11 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-2012-6461 1 Opera 1 Opera Browser 2025-04-11 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-2006-6955 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera allows remote attackers to cause a denial of service (application crash) via a web page that contains a large number of nested marquee tags, a related issue to CVE-2006-2723.
CVE-2009-3045 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera before 10.00 trusts root X.509 certificates signed with the MD2 algorithm, which makes it easier for man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted server certificate.
CVE-2007-3819 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera 9.21 allows remote attackers to spoof the data: URI scheme in the address bar via a long URI with trailing whitespace, which prevents the beginning of the URI from being displayed.
CVE-2009-3013 1 Opera 1 Opera Browser 2025-04-09 N/A
Opera 9.52 and earlier, and 10.00 Beta 3 Build 1699, does not properly block data: URIs in Location headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Location header. NOTE: the JavaScript executes outside of the context of the HTTP site.
CVE-2007-0126 1 Opera 1 Opera Browser 2025-04-09 N/A
Heap-based buffer overflow in Opera 9.02 allows remote attackers to execute arbitrary code via a JPEG file with an invalid number of index bytes in the Define Huffman Table (DHT) marker.
CVE-2007-0127 1 Opera 1 Opera Browser 2025-04-09 N/A
The Javascript SVG support in Opera before 9.10 does not properly validate object types in a createSVGTransformFromMatrix request, which allows remote attackers to execute arbitrary code via JavaScript code that uses an invalid object in this request that causes a controlled pointer to be referenced during the virtual function call.
