Description:
mikx has discovered three vulnerabilities in Netscape, which can be exploited by malicious people to plant malware on a user's system, conduct cross-site scripting attacks and bypass certain security restrictions.
1) Netscape validates an image against the "Content-Type" HTTP header, but uses the file extension from the URL when saving an image after a drag and drop event. This can e.g. be exploited to plant a valid image with an arbitrary file extension and embedded script code (e.g. .bat file) on the desktop by tricking a user into performing a certain drag and drop event.
2) Missing URI handler validation when dragging a "javascript:" URL to another tab can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an arbitrary site by tricking a user into dragging a malicious link to another tab.
3) An error in the restriction of URI handlers loaded via plugins can be exploited to link to certain restricted URIs (e.g. about:config).
This can further be exploited to trick a user into changing some sensitive configuration settings.
The vulnerabilities have been confirmed in version 7.2. Other versions may also be affected.
