Mozilla Firefox, SeaMonkey, XULRunner: Multiple vulnerabilities

Background

Mozilla Firefox is a cross-platform web browser from Mozilla. SeaMonkey is a free, cross-platform Internet suite.

Description

Multiple vulnerabilities have been reported in Mozilla Firefox and SeaMonkey. Various errors in the browser engine and the Javascript engine can be exploited to cause a memory corruption (CVE-2007-5339 and CVE-2007-5340). Before being used in a request, input passed to the user ID when making an HTTP request with digest authentication is not properly sanitised (CVE-2007-2292). The titlebar can be hidden by a XUL markup language document (CVE-2007-5334). Additionally, an error exists in the handling of “smb:” and “sftp:” URI schemes on systems with gnome-vfs support (CVE-2007-5337). An unspecified error in the handling of “XPCNativeWrappers” and not properly implementing JavaScript onUnload() handlers may allow the execution of arbitrary Javascript code (CVE-2007-5338 and CVE-2007-1095). Another error is triggered by using the addMicrosummaryGenerator sidebar method to access file: URIs (CVE-2007-5335).

Impact

A remote attacker could exploit these issues to execute arbitrary code, gain the privileges of the user running the application, disclose sensitive information, conduct phishing attacks, and read and manipulate certain data.

Workaround

There is no known workaround at this time.
