Mozilla Firefox is an open-source web browser from the Mozilla Project, and Mozilla Thunderbird an email client. The SeaMonkey project is a community effort to deliver production-quality releases of code derived from the application formerly known as the 'Mozilla Application Suite'. XULRunner is a Mozilla runtime package that can be used to bootstrap XUL+XPCOM applications like Firefox and Thunderbird.
Mozilla developers fixed several bugs, including an issue with modifying XPCNativeWrappers (CVE-2007-3738), a problem with event handlers executing elements outside of the document (CVE-2007-3737), and a cross-site scripting (XSS) vulnerability (CVE-2007-3736). They also fixed a problem with promiscuous IFRAME access (CVE-2007-3089) and an XULRunner URL spoofing issue with the wyciwyg:// URI and HTTP 302 redirects (CVE-2007-3656). Denials of Service involving corrupted memory were fixed in the browser engine (CVE-2007-3734) and the JavaScript engine (CVE-2007-3735). Finally, another XSS vulnerability caused by a regression in the CVE-2007-3089 patch was fixed (CVE-2007-3844).
A remote attacker could entice a user to view a specially crafted web page that will trigger one of the vulnerabilities, possibly leading to the execution of arbitrary code or a Denial of Service. It is also possible for an attacker to perform cross-site scripting attacks, which could result in the exposure of sensitive information such as login credentials.
There is no known workaround at this time.
