Unspecified vulnerability in the Java Runtime Environment component in Oracle Java SE JDK and JRE 7, 6 Update 27 and earlier, 5.0 Update 31 and earlier, and 1.4.2_33 and earlier allows remote attackers to affect integrity via unknown vectors related to Networking.

Firefox before 1.0.1 and Mozilla before 1.7.6 allows remote malicious web sites to spoof the extensions of files to download via the Content-Disposition header, which could be used to trick users into downloading dangerous content.

Firefox before 1.0.1 allows remote attackers to spoof the (1) security and (2) download modal dialog boxes, which could be used to trick users into executing script or downloading and executing a file, aka "Firespoofing."

When network partitioning was enabled, e.g. as a result of Enhanced Tracking Protection settings, a TLS error page would allow the user to override an error on a domain which had specified HTTP Strict Transport Security (which implies that the error should not be override-able.) This issue did not affect the network connections, and they were correctly upgraded to HTTPS automatically. This vulnerability affects Firefox < 90.

Opera 7.x and 8 before 8.01 does not clearly associate a Javascript dialog box with the web page that generated it, which allows remote attackers to spoof a dialog box from a trusted site and facilitates phishing attacks, aka the "Dialog Origin Spoofing Vulnerability."

Firefox before 1.0 and Mozilla before 1.7.5 display the secure site lock icon when a view-source: URL references a secure SSL site while an insecure page is being loaded, which could facilitate phishing attacks.
