Mozilla before 1.7, Firefox before 0.9, and Thunderbird before 0.7, allow remote attackers to use certain redirect sequences to spoof the security lock icon that makes a web page appear to be encrypted.
Mozilla before 1.7, Firefox before 0.9, and Thunderbird before 0.7, allow remote web sites to install arbitrary extensions by using interactive events to manipulate the XPInstall Security dialog box.
Mozilla before 1.7, Firefox before 0.9, and Thunderbird before 0.7, allow remote web sites to hijack the user interface via the "chrome" flag and XML User Interface Language (XUL) files.
The cert_TestHostName function in Mozilla before 1.7, Firefox before 0.9, and Thunderbird before 0.7, only checks the hostname portion of a certificate when the hostname portion of the URI is not a fully qualified domain name (FQDN), which allows remote attackers to spoof trusted certificates.
The (1) Mozilla 1.6, (2) Firebird 0.7 and (3) Firefox 0.8 web browsers do not properly verify that cached passwords for SSL encrypted sites are only sent via SSL encrypted sessions to the site, which allows a remote attacker to cause a cached password to be sent in cleartext to a spoofed site.
Mozilla (Suite) before 1.7.1, Firefox before 0.9.2, and Thunderbird before 0.7.2 allow remote attackers to launch arbitrary programs via a URI referencing the shell: protocol.
The (1) Mozilla 1.6, (2) Firebird 0.7, (3) Firefox 0.8, and (4) Netscape 7.1 web browsers do not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates web site spoofing and other attacks, aka the frame injection vulnerability.
Unknown versions of Mozilla allow remote attackers to cause a denial of service (high CPU/RAM consumption) using Javascript with an infinite loop that continues to add input to a form, possibly as the result of inserting control characters, as demonstrated using an embedded ctrl-U.
Mozilla allows remote attackers to bypass intended cookie access restrictions on a web application via "%2e%2e" (encoded dot dot) directory traversal sequences in a URL, which causes Mozilla to send the cookie outside the specified URL subsets, e.g. to a vulnerable application that runs on the same server as the target application.
