CVE-2007-2809 1 Opera 1 Opera Browser 2022-02-25 9.3 HIGH N/A
Buffer overflow in the transfer manager in Opera before 9.21 for Windows allows user-assisted remote attackers to execute arbitrary code via a crafted torrent file. NOTE: due to the lack of details, it is not clear if this is the same issue as CVE-2007-2274.
CVE-2007-4367 1 Opera 1 Opera Browser 2022-02-25 9.3 HIGH N/A
Opera before 9.23 allows remote attackers to execute arbitrary code via crafted Javascript that triggers a "virtual function call on an invalid pointer."
CVE-2007-3929 1 Opera 1 Opera Browser 2022-02-25 9.3 HIGH N/A
Use-after-free vulnerability in the BitTorrent support in Opera before 9.22 allows user-assisted remote attackers to execute arbitrary code via a crafted header in a torrent file, which leaves a dangling pointer to an invalid object.
CVE-2003-1420 1 Opera 1 Opera Browser 2022-02-24 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera 6.0 through 7.0 with automatic redirection disabled allows remote attackers to inject arbitrary web script or HTML via the HTTP Location header.
CVE-2010-2657 3 Apple, Microsoft, Opera 3 Macos, Windows, Opera Browser 2021-09-08 9.3 HIGH N/A
Opera before 10.60 on Windows and Mac OS X does not properly prevent certain double-click operations from running a program located on a web site, which allows user-assisted remote attackers to execute arbitrary code via a crafted web page that bypasses a dialog.
CVE-2018-18913 2 Microsoft, Opera 2 Windows 7, Opera Browser 2019-09-27 6.9 MEDIUM 7.8 HIGH
Opera before 57.0.3098.106 is vulnerable to a DLL Search Order hijacking attack where an attacker can send a ZIP archive composed of an HTML page along with a malicious DLL to the target. Once the document is opened, it may allow the attacker to take full control of the system from any location within the system. The issue lies in the loading of the shcore.dll and dcomp.dll files: these files are being searched for by the program in the same system-wide directory where the HTML file is executed.
CVE-2010-2659 4 Apple, Microsoft, Opera and 1 more 4 Mac Os X, Windows, Opera Browser and 1 more 2018-10-30 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-2010-2666 3 Apple, Microsoft, Opera 3 Mac Os X, Windows, Opera Browser 2018-10-30 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-2009-3047 1 Opera 1 Opera Browser 2018-10-30 4.3 MEDIUM N/A
Opera before 10.00, when a collapsed address bar is used, does not properly update the domain name from the previously visited site to the currently visited site, which might allow remote attackers to spoof URLs.
CVE-2010-2421 1 Opera 1 Opera Browser 2018-10-30 10.0 HIGH N/A
Multiple unspecified vulnerabilities in Opera before 10.54 have unknown impact and attack vectors related to (1) "extremely severe," (2) "highly severe," (3) "moderately severe," and (4) "less severe" issues.
CVE-2010-2665 4 Apple, Microsoft, Opera and 1 more 4 Mac Os X, Windows, Opera Browser and 1 more 2018-10-30 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera before 10.54 on Windows and Mac OS X, and before 10.11 on UNIX platforms, allows remote attackers to inject arbitrary web script or HTML via a data: URI, related to incorrect detection of the "opening site."
CVE-2010-2658 1 Opera 1 Opera Browser 2018-10-30 4.3 MEDIUM N/A
Opera before 10.60 does not properly restrict certain interaction between plug-ins, file inputs, and the clipboard, which allows user-assisted remote attackers to trigger the uploading of arbitrary files via a crafted web site.
CVE-2010-2662 1 Opera 1 Opera Browser 2018-10-30 4.3 MEDIUM N/A
Opera before 10.60 allows remote attackers to bypass the popup blocker via a javascript: URL and a "fake click."
CVE-2009-4072 1 Opera 1 Opera Browser 2018-10-30 10.0 HIGH N/A
Unspecified vulnerability in Opera before 10.10 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 2018-10-30 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-2010-2663 1 Opera 1 Opera Browser 2018-10-30 4.3 MEDIUM N/A
Opera before 10.60 allows remote attackers to cause a denial of service (application hang) via an ended event handler that changes the SRC attribute of an AUDIO element.
CVE-2010-2660 4 Apple, Microsoft, Opera and 1 more 4 Mac Os X, Windows, Opera Browser and 1 more 2018-10-30 4.3 MEDIUM N/A
Opera before 10.54 on Windows and Mac OS X, and before 10.60 on UNIX platforms, does not properly restrict certain uses of homograph characters in domain names, which makes it easier for remote attackers to spoof IDN domains via unspecified choices of characters.
CVE-2010-2661 4 Apple, Microsoft, Opera and 1 more 4 Mac Os X, Windows, Opera Browser and 1 more 2018-10-30 4.3 MEDIUM N/A
Opera before 10.54 on Windows and Mac OS X, and before 10.60 on UNIX platforms, does not properly restrict access to the full pathname of a file selected for upload, which allows remote attackers to obtain potentially sensitive information via unspecified DOM manipulations.
CVE-2006-6955 1 Opera 1 Opera Browser 2018-10-30 4.3 MEDIUM 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-2007-5274 3 Mozilla, Opera, Sun 5 Firefox, Opera Browser, Jdk and 2 more 2018-10-30 2.6 LOW N/A
Sun Java Runtime Environment (JRE) in JDK and JRE 6 Update 2 and earlier, JDK and JRE 5.0 Update 12 and earlier, SDK and JRE 1.4.2_15 and earlier, and SDK and JRE 1.3.1_20 and earlier, when Firefox or Opera is used, allows remote attackers to violate the security model for JavaScript outbound connections via a multi-pin DNS rebinding attack dependent on the LiveConnect API, in which JavaScript download relies on DNS resolution by the browser, but JavaScript socket operations rely on separate DNS resolution by a Java Virtual Machine (JVM), a different issue than CVE-2007-5273. NOTE: this is similar to CVE-2007-5232.
