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-2016-4075 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-2016-5101 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-2016-7152 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-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-2016-7153 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-2010-4049 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 10.63 allows remote attackers to cause a denial of service (application crash) via a Flash movie with a transparent Window Mode (aka wmode) property, which is not properly handled during navigation away from the containing HTML document.
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-2012-4010 1 Opera 1 Opera Browser 2025-04-11 N/A

CVE-2012-3561 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.64 does not properly allocate memory for URL strings, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted string.

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-2012-1251 1 Opera 1 Opera Browser 2025-04-11 N/A

Opera before 12.13 allows remote attackers to execute arbitrary code via vectors involving DOM events.
