CVE-2011-2634 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Opera before 11.10 allows remote attackers to hijack (1) searches and (2) customizations via unspecified third party applications.
CVE-2013-1618 1 Opera 1 Opera Browser 2025-04-11 4.0 MEDIUM N/A
The TLS implementation in Opera before 12.13 does not properly consider timing side-channel attacks on a MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169.
CVE-2011-4685 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Dragonfly in Opera before 11.60 allows remote attackers to cause a denial of service (application crash) via unspecified content on a web page, as demonstrated by forbes.com.
CVE-2010-2455 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
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.
CVE-2010-4046 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
Opera before 10.63 does not properly verify the origin of video content, which allows remote attackers to obtain sensitive information by using a video stream as HTML5 canvas content.
CVE-2010-4582 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Opera before 11.00 does not properly handle security policies during updates to extensions, which might allow remote attackers to bypass intended access restrictions via unspecified vectors.
CVE-2011-2624 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
Opera before 11.50 allows user-assisted remote attackers to cause a denial of service (application hang) via a large table, which is not properly handled during a print preview.
CVE-2012-4142 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, 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.
CVE-2012-6468 1 Opera 1 Opera Browser 2025-04-11 9.3 HIGH N/A
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.
CVE-2012-1924 1 Opera 1 Opera Browser 2025-04-11 6.8 MEDIUM 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-2010-4579 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Opera before 11.00 does not properly constrain dialogs to appear on top of rendered documents, which makes it easier for remote attackers to trick users into interacting with a crafted web site that spoofs the (1) security information dialog or (2) download dialog.
CVE-2011-2613 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
The Array.prototype.join method in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via a non-array object that contains initial holes.
CVE-2012-3558 1 Opera 1 Opera Browser 2025-04-11 2.6 LOW N/A
Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during unusually timed changes to this field, which makes it easier for user-assisted remote attackers to conduct spoofing attacks via vectors involving navigation, reloads, and redirects.
CVE-2011-0682 1 Opera 1 Opera Browser 2025-04-11 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-2012-1930 2 Opera, Unix 2 Opera Browser, Unix 2025-04-11 4.6 MEDIUM N/A
Opera before 11.62 on UNIX uses world-readable permissions for temporary files during printing, which allows local users to obtain sensitive information by reading these files.
CVE-2010-2666 3 Apple, Microsoft, Opera 3 Mac Os X, Windows, Opera Browser 2025-04-11 9.3 HIGH N/A
Opera before 10.54 on Windows and Mac OS X does not properly enforce permission requirements for widget filesystem access and directory selection, which allows user-assisted remote attackers to create or modify arbitrary files, and consequently execute arbitrary code, via widget File I/O operations.
CVE-2011-2621 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors related to form layout.
CVE-2010-1310 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Opera 10.50 allows remote attackers to obtain sensitive information via crafted XSLT constructs, which cause Opera to return cached contents of other pages.
CVE-2012-4010 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Opera before 11.60 allows remote attackers to spoof the address bar via unspecified homograph characters, a different vulnerability than CVE-2010-2660.
CVE-2011-1824 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
The VEGAOpBitmap::AddLine function in Opera before 10.61 does not properly initialize memory during processing of the SIZE attribute of a SELECT element, which allows remote attackers to trigger an invalid memory write operation, and consequently cause a denial of service (application crash) or possibly execute arbitrary code, via a large integer attribute value.
