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-2018-16135 1 Opera 1 Opera Mini 2025-04-14 6.5 Medium
The Opera Mini application 47.1.2249.129326 for Android allows remote attackers to spoof the Location Permission dialog via a crafted web site.
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-2016-7152 5 Apple, Google, Microsoft and 2 more 6 Safari, Chrome, Edge and 3 more 2025-04-12 N/A
The HTTPS 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-2016-5101 2 Microsoft, Opera 2 Windows, Opera Mail 2025-04-12 N/A
Unspecified vulnerability in Opera Mail before 2016-02-16 on Windows allows user-assisted remote attackers to execute arbitrary code via a crafted e-mail message.
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-2010-2121 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera 9.52 allows remote attackers to cause a denial of service (resource consumption) via JavaScript code containing an infinite loop that creates IFRAME elements for invalid (1) news:// or (2) nntp:// URIs.
CVE-2012-3564 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 12.00 Beta allows remote attackers to cause a denial of service (application hang) via an absolutely positioned wrap=off TEXTAREA element located next to an "overflow: auto" block element.
CVE-2010-1989 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera 9.52 executes a mail application in situations where an IMG element has a SRC attribute that is a redirect to a mailto: URL, which allows remote attackers to cause a denial of service (excessive application launches) via an HTML document with many images, a related issue to CVE-2010-0181.
CVE-2012-3555 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.65 does not ensure that keyboard sequences are associated with a visible window, which makes it easier for user-assisted remote attackers to conduct cross-site scripting (XSS) attacks or execute arbitrary code via a crafted web site, related to a "hidden keyboard navigation" issue.
CVE-2012-3565 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 12.00 Beta allows remote attackers to cause a denial of service (application crash) via crafted characters in domain names, as demonstrated by "IDNA2008 tests."
CVE-2010-1993 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera 9.52 does not properly handle an IFRAME element with a mailto: URL in its SRC attribute, which allows remote attackers to cause a denial of service (resource consumption) via an HTML document with many IFRAME elements.
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-2013-1489 6 Google, Microsoft, Mozilla and 3 more 7 Chrome, Internet Explorer, Firefox and 4 more 2025-04-11 N/A
Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 10 and Update 11, when running on Windows using Internet Explorer, Firefox, Opera, and Google Chrome, allows remote attackers to bypass the "Very High" security level of the Java Control Panel and execute unsigned Java code without prompting the user via unknown vectors, aka "Issue 53" and the "Java Security Slider" vulnerability.
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-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-2012-3557 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.65 does not properly restrict the reading of JSON strings, which allows remote attackers to perform cross-domain loading of JSON resources and consequently obtain sensitive information via a crafted web site.
CVE-2012-4143 4 Apple, Linux, Microsoft and 1 more 4 Mac Os X, Linux Kernel, Windows and 1 more 2025-04-11 N/A
