Opera before 9.51 does not properly manage memory within functions supporting the CANVAS element, which allows remote attackers to read uninitialized memory contents by using JavaScript to read a canvas image.

Opera, probably before 7.50, sends Referer headers containing https:// URLs in requests for http:// URLs, which allows remote attackers to obtain potentially sensitive information by reading Referer log data.

Adobe Macromedia Flash Player 7 and 9, when used with Opera before 9.20 or Konqueror before 20070613, allows remote attackers to obtain sensitive information (browser keystrokes), which are leaked to the Flash Player applet.

The FTP protocol implementation in Opera 9.10 allows remote attackers to allows remote servers to force the client to connect to other servers, perform a proxied port scan, or obtain sensitive information by specifying an alternate server address in an FTP PASV response.

Opera before 12.11 allows remote attackers to determine the existence of arbitrary local files via vectors involving web script in an error page.

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.

The intent: URL implementation in Opera before 18 on Android allows attackers to read local files by leveraging an interaction error, as demonstrated by reading stored cookies.

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.

The Opera Mobile application before 12.1 and Opera Mini application before 7.5 for Android do not properly implement the WebView class, which allows attackers to obtain sensitive information via a crafted application.

Opera before 11.00 does not clear WAP WML form fields after manual navigation to a new web site, which allows remote attackers to obtain sensitive information via an input field that has the same name as an input field on a previously visited web site.

Opera before 10.50 on Windows, before 10.52 on Mac OS X, and before 10.60 on UNIX platforms makes widget properties accessible to third-party domains, which allows remote attackers to obtain potentially sensitive information via a crafted web site.

Opera before 11.62 allows remote attackers to bypass the Same Origin Policy via the (1) history.pushState and (2) history.replaceState functions in conjunction with cross-domain frames, leading to unintended read access to history.state information.

Opera before 9.52 does not prevent use of links from web pages to feed source files on the local disk, which might allow remote attackers to determine the validity of local filenames via vectors involving "detection of JavaScript events and appropriate manipulation."

Unspecified vulnerability in Opera before 9.63 allows remote attackers to "reveal random data" via unknown vectors.

In the WebRTC component in Opera 51.0.2830.55, after visiting a web site that attempts to gather complete client information (such as https://ip.voidsec.com), the browser can disclose a private IP address in a STUN request.

Opera before 9.25 allows remote attackers to obtain potentially sensitive memory contents via a crafted bitmap (BMP) file, as demonstrated using a CANVAS element and JavaScript in an HTML document for copying these contents from 9.50 beta, a related issue to CVE-2008-0420.

Cybozu Mailwise before 5.4.0 allows remote attackers to conduct clickjacking attacks.

Mbedthis AppWeb before 2.2.2 enables the HTTP TRACE method, which has unspecified impact probably related to remote information leaks and cross-site tracing (XST) attacks, a related issue to CVE-2004-2320 and CVE-2005-3398.

Microsoft Internet Explorer 5.01 SP4 and 6 SP1 and earlier allows remote attackers to conduct spoofing and phishing attacks by using a modal browser window in a way that preserves the original address bar and trusted UI of a trusted site, even after the browser has been navigated to a malicious site, aka the "Address Bar Spoofing Vulnerability."

The vulnerability allows a successful attacker to bypass the integrity check of FW uploaded to the free@home System Access Point.

The OpenConnectionTask::handleStateHelper function in Imap/Tasks/OpenConnectionTask.cpp in Trojita before 0.4.1 allows man-in-the-middle attackers to trigger use of cleartext for saving a message into a (1) sent or (2) draft folder via a PREAUTH response that prevents later use of the STARTTLS command.

Microsoft Enhanced Mitigation Experience Toolkit (EMET) before 4.0 uses predictable addresses for hooked functions, which makes it easier for context-dependent attackers to defeat the ASLR protection mechanism via a return-oriented programming (ROP) attack.

Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a privileged network position to potentially exploit heap corruption via a crafted SCTP stream.

: Information Exposure vulnerability in itemlookup.asp of Telos Automated Message Handling System allows a remote attacker to inject arbitrary script into an AMHS session. This issue affects: Telos Automated Message Handling System versions prior to 4.1.5.5.

A bypass vulnerability in Active Storage >= 5.2.0 for Google Cloud Storage and Disk services allow an attacker to modify the `content-disposition` and `content-type` parameters which can be used in with HTML files and have them executed inline. Additionally, if combined with other techniques such as cookie bombing and specially crafted AppCache manifests, an attacker can gain access to private signed URLs within a specific storage path. This vulnerability has been fixed in version 5.2.1.1.
