Firefox before 1.0.7 and Mozilla Suite before 1.7.12 allows remote attackers to spoof DOM objects via an XBL control that implements an internal XPCOM interface.
Integer overflow in the JavaScript engine in Firefox before 1.0.7 and Mozilla Suite before 1.7.12 might allow remote attackers to execute arbitrary code.
Firefox before 1.0.7 and Mozilla before Suite 1.7.12 allows remote attackers to execute Javascript with chrome privileges via an about: page such as about:mozilla.
Firefox before 1.0.7 and Mozilla Suite before 1.7.12 allows remote attackers to spawn windows without user interface components such as the address and status bar, which could be used to conduct spoofing or phishing attacks.
Firefox 1.0.6 and Mozilla 1.7.10 allows attackers to execute arbitrary commands via shell metacharacters in a URL that is provided to the browser on the command line, which is sent unfiltered to bash.
Buffer overflow in the International Domain Name (IDN) support in Mozilla Firefox 1.0.6 and earlier, and Netscape 8.0.3.3 and 7.2, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a hostname with all "soft" hyphens (character 0xAD), which is not properly handled by the NormalizeIDN call in nsStandardURL::BuildNormalizedSpec.
Mozilla Thunderbird 1.0 and Firefox 1.0.6 allows remote attackers to obfuscate URIs via a long URI, which causes the address bar to go blank and could facilitate phishing attacks.
Firefox, when opening Microsoft Word documents, does not properly set the permissions on shared sections, which allows remote attackers to write arbitrary data to open applications in Microsoft Office.
Mozilla Firefox 1.0.4 and 1.0.5 does not choose the challenge with the strongest authentication scheme available as required by RFC2617, which might cause credentials to be sent in plaintext even if an encrypted channel is available.
The browser user interface in Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 and 7.2 does not properly distinguish between user-generated events and untrusted synthetic events, which makes it easier for remote attackers to perform dangerous actions that normally could only be performed manually by the user.
