CVE-2007-2274 1 Opera 1 Opera Browser 2022-02-25 7.8 HIGH N/A
The BitTorrent implementation in Opera 9.2 allows remote attackers to cause a denial of service (CPU consumption and application crash) via a malformed torrent file. NOTE: the original disclosure refers to this as a memory leak, but it is not certain.
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-2019-18624 1 Opera 1 Mini 2021-07-21 7.5 HIGH 9.8 CRITICAL
Opera Mini for Android allows attackers to bypass intended restrictions on .apk file download/installation via an RTLO (aka Right to Left Override) approach, as demonstrated by misinterpretation of malicious%E2%80%AEtxt.apk as maliciouskpa.txt. This affects 44.1.2254.142553, 44.1.2254.142659, and 44.1.2254.143214.
CVE-2021-23253 1 Opera 1 Opera Mini 2021-01-19 5.0 MEDIUM 5.3 MEDIUM
Opera Mini for Android below 53.1 displays URL left-aligned in the address field. This allows a malicious attacker to craft a URL with a long domain name, e.g. www.safe.opera.com.attacker.com. With the URL being left-aligned, the user will only see the front part (e.g. www.safe.opera.com…) The exact amount depends on the phone screen size but the attacker can craft a number of different domains and target different phones. Starting with version 53.1 Opera Mini displays long URLs with the top-level domain label aligned to the right of the address field which mitigates the issue.
CVE-2020-6159 1 Opera 1 Opera 2020-12-23 4.3 MEDIUM 6.1 MEDIUM
URLs using “javascript:” have the protocol removed when pasted into the address bar to protect users from cross-site scripting (XSS) attacks, but in certain circumstances this removal was not performed. This could allow users to be socially engineered to run an XSS attack against themselves. This vulnerability affects Opera for Android versions below 61.0.3076.56532.
CVE-2020-6157 1 Opera 1 Opera Touch 2020-11-30 4.3 MEDIUM 4.3 MEDIUM
Opera Touch for iOS before version 2.4.5 is vulnerable to an address bar spoofing attack. The vulnerability allows a malicious page to trick the browser into showing an address of a different page. This may allow the malicious page to impersonate another page and trick a user into providing sensitive data.
CVE-2019-12278 1 Opera 1 Opera 2020-08-24 4.3 MEDIUM 4.3 MEDIUM
Opera through 53 on Android allows Address Bar Spoofing. Characters from several languages are displayed in Right-to-Left order, due to mishandling of several Unicode characters. The rendering mechanism, in conjunction with the "first strong character" concept, may improperly operate on a numerical IP address or an alphabetic string, leading to a spoofed URL.
CVE-2019-19788 1 Opera 1 Opera 2020-01-07 2.1 LOW 5.5 MEDIUM
Opera for Android before 54.0.2669.49432 is vulnerable to a sandboxed cross-origin iframe bypass attack. By using a service working inside a sandboxed iframe it is possible to bypass the normal sandboxing attributes. This allows an attacker to make forced redirections without any user interaction from a third-party context.
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-2019-13607 1 Opera 1 Mini 2019-08-01 4.3 MEDIUM 6.1 MEDIUM
The Opera Mini application through 16.0.14 for iOS has a UXSS vulnerability that can be triggered by performing navigation to a javascript: URL.
CVE-2009-3049 1 Opera 1 Opera Browser 2018-10-30 5.0 MEDIUM N/A
Opera before 10.00 does not properly display all characters in Internationalized Domain Names (IDN) in the address bar, which allows remote attackers to spoof URLs and conduct phishing attacks, related to Unicode and Punycode.
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-2010-2666 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-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-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-2009-3013 1 Opera 1 Opera Browser 2018-10-30 4.3 MEDIUM 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.
