CVE-2016-4075 1 Opera 2 Opera Browser, Opera Mini 2025-04-20 6.1 Medium
Opera Mini 13 and Opera Stable 36 allow remote attackers to spoof the displayed URL via a crafted HTML document, related to the about:blank URL.
CVE-2016-6908 1 Opera 1 Opera Browser 2025-04-20 N/A
Characters from languages are such as Arabic, Hebrew are displayed from RTL (Right To Left) order in Opera 37.0.2192.105088 for Android, due to mishandling of several unicode characters such as U+FE70, U+0622, U+0623 etc and how they are rendered combined with (first strong character) such as an IP address or alphabet could lead to a spoofed URL. It was noticed that by placing neutral characters such as "/", "?" in filepath causes the URL to be flipped and displayed from Right To Left. However, in order for the URL to be spoofed the URL must begin with an IP address followed by neutral characters as omnibox considers IP address to be combination of punctuation and numbers and since LTR (Left To Right) direction is not properly enforced, this causes the entire URL to be treated and rendered from RTL (Right To Left). However, it doesn't have be an IP address, what matters is that first strong character (generally, alphabetic character) in the URL must be an RTL character.
CVE-2016-7153 5 Apple, Google, Microsoft and 2 more 6 Safari, Chrome, Edge and 3 more 2025-04-12 N/A
The HTTP/2 protocol does not consider the role of the TCP congestion window in providing information about content length, which makes it easier for remote attackers to obtain cleartext data by leveraging a web-browser configuration in which third-party cookies are sent, aka a "HEIST" attack.
CVE-2015-4000 13 Apple, Canonical, Debian and 10 more 31 Iphone Os, Mac Os X, Safari and 28 more 2025-04-12 N/A
The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.
CVE-2015-8960 7 Apple, Google, Ietf and 4 more 18 Safari, Chrome, Transport Layer Security and 15 more 2025-04-12 8.1 High
The TLS protocol 1.2 and earlier supports the rsa_fixed_dh, dss_fixed_dh, rsa_fixed_ecdh, and ecdsa_fixed_ecdh values for ClientCertificateType but does not directly document the ability to compute the master secret in certain situations with a client secret key and server public key but not a server secret key, which makes it easier for man-in-the-middle attackers to spoof TLS servers by leveraging knowledge of the secret key for an arbitrary installed client X.509 certificate, aka the "Key Compromise Impersonation (KCI)" issue.
CVE-2010-2421 1 Opera 1 Opera Browser 2025-04-11 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-2010-0653 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 10.10 permits cross-origin loading of CSS stylesheets even when the stylesheet download has an incorrect MIME type and the stylesheet document is malformed, which allows remote attackers to obtain sensitive information via a crafted document.
CVE-2010-4046 1 Opera 1 Opera Browser 2025-04-11 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-2011-2637 1 Opera 1 Opera Browser 2025-04-11 N/A
Unspecified vulnerability in Opera before 11.10 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by futura-sciences.com, seoptimise.com, and mitosyfraudes.org.
CVE-2011-2623 1 Opera 1 Opera Browser 2025-04-11 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.
CVE-2011-2640 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.10 allows remote attackers to cause a denial of service (application crash) via an HTML document that has an empty parameter value for an embedded Java applet.
CVE-2011-2617 1 Opera 1 Opera Browser 2025-04-11 N/A
Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors related to selecting a text node, and closed pop-up windows, removed pop-up windows, and IFRAME elements.
CVE-2011-2627 1 Opera 1 Opera Browser 2025-04-11 N/A
Unspecified vulnerability in the DOM implementation in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by live.com.
CVE-2010-1349 2 Microsoft, Opera 2 Windows, Opera Browser 2025-04-11 N/A
Integer overflow in Opera 10.10 through 10.50 allows remote attackers to execute arbitrary code via a large Content-Length value, which triggers a heap overflow.
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-2012-6466 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 12.10 does not properly handle incorrect size data in a WebP image, which allows remote attackers to obtain potentially sensitive information from process memory by using a crafted image as the fill pattern for a canvas.
CVE-2011-4690 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera 11.60 and earlier does not prevent capture of data about the times of Same Origin Policy violations during IFRAME loading attempts, which makes it easier for remote attackers to determine whether a document exists in the browser cache via crafted JavaScript code.
CVE-2011-2631 1 Opera 1 Opera Browser 2025-04-11 N/A
The Cascading Style Sheets (CSS) implementation in Opera before 11.11 does not properly handle the column-count property, which allows remote attackers to cause a denial of service (infinite repaint loop and application hang) via a web page, as demonstrated by an unspecified Wikipedia page.
