CVE-2006-4819 1 Opera 1 Opera Browser 2017-07-19 5.1 MEDIUM N/A
Heap-based buffer overflow in Opera 9.0 and 9.01 allows remote attackers to execute arbitrary code via a long URL in a tag (long link address).
CVE-2005-3006 1 Opera 1 Opera Browser 2017-07-10 5.0 MEDIUM N/A
The mail client in Opera before 8.50 opens attached files from the user's cache directory without warning the user, which might allow remote attackers to inject arbitrary web script and spoof attachment filenames.
CVE-2016-7153 5 Apple, Google, Microsoft and 2 more 6 Safari, Chrome, Edge and 3 more 2017-02-18 5.0 MEDIUM 5.3 MEDIUM
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-2016-6908 1 Opera 1 Opera Browser 2017-01-27 5.8 MEDIUM 6.1 MEDIUM
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-2012-6469 1 Opera 1 Opera Browser 2015-10-08 5.0 MEDIUM N/A
Opera before 12.11 allows remote attackers to determine the existence of arbitrary local files via vectors involving web script in an error page.
CVE-2012-6468 1 Opera 1 Opera Browser 2015-10-08 9.3 HIGH N/A
Heap-based buffer overflow in Opera before 12.11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a long HTTP response.
CVE-2012-6467 1 Opera 1 Opera Browser 2015-09-29 4.3 MEDIUM N/A
Opera before 12.10 follows Internet shortcuts that are referenced by a (1) IMG element or (2) other inline element, which makes it easier for remote attackers to conduct phishing attacks via a crafted web site, as exploited in the wild in November 2012.
CVE-2012-1251 1 Opera 1 Opera Browser 2014-03-05 5.8 MEDIUM N/A
Opera before 9.63 does not properly verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.
CVE-2014-1870 2 Apple, Opera 2 Mac Os X, Opera Browser 2014-02-07 4.3 MEDIUM N/A
Opera before 19 on Mac OS X allows user-assisted remote attackers to spoof the address bar via vectors involving a drag-and-drop operation.
CVE-2013-4705 1 Opera 1 Opera Browser 2013-09-13 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera before 15.00 allows remote attackers to inject arbitrary web script or HTML by leveraging UTF-8 encoding.
CVE-2013-3210 1 Opera 1 Opera Browser 2013-04-22 5.0 MEDIUM N/A
Opera before 12.15 does not properly block top-level domains in Set-Cookie headers, which allows remote attackers to obtain sensitive information by leveraging control of a different web site in the same top-level domain.
CVE-2013-3211 1 Opera 1 Opera Browser 2013-04-21 10.0 HIGH N/A
Unspecified vulnerability in Opera before 12.15 has unknown impact and attack vectors, related to a "moderately severe issue."
CVE-2013-1618 1 Opera 1 Opera Browser 2013-03-07 4.0 MEDIUM N/A
The TLS implementation in Opera before 12.13 does not properly consider timing side-channel attacks on a MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169.
CVE-2013-1639 1 Opera 1 Opera Browser 2013-03-07 6.8 MEDIUM N/A
Opera before 12.13 does not send CORS preflight requests in all required cases, which allows remote attackers to bypass a CSRF protection mechanism via a crafted web site that triggers a CORS request.
CVE-2013-1638 1 Opera 1 Opera Browser 2013-03-07 9.3 HIGH N/A
Opera before 12.13 allows remote attackers to execute arbitrary code via crafted clipPaths in an SVG document.
CVE-2013-1637 1 Opera 1 Opera Browser 2013-03-07 9.3 HIGH N/A
Opera before 12.13 allows remote attackers to execute arbitrary code via vectors involving DOM events.
CVE-2012-6470 1 Opera 1 Opera Browser 2013-01-02 9.3 HIGH N/A
Opera before 12.12 does not properly allocate memory for GIF images, which allows remote attackers to execute arbitrary code or cause a denial of service (memory overwrite) via a malformed image.
CVE-2012-6466 1 Opera 1 Opera Browser 2013-01-02 5.0 MEDIUM 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-2012-6465 1 Opera 1 Opera Browser 2013-01-02 9.3 HIGH N/A
Opera before 12.10 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a malformed SVG image.
CVE-2012-6463 1 Opera 1 Opera Browser 2013-01-02 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera before 12.10 allows remote attackers to inject arbitrary web script or HTML via vectors involving an unspecified sequence of loading of documents and loading of data: URLs.
