Background
Mozilla is a popular web browser that includes a mail and newsreader. Mozilla Firefox and Mozilla Thunderbird are respectively the next-generation browser and mail client from the Mozilla project.
Description
Maurycy Prodeus from isec.pl found a potentially exploitable buffer overflow in the handling of NNTP URLs. Furthermore, Martin (from ptraced.net) discovered that temporary files in recent versions of Mozilla-based products were sometimes stored world-readable with predictable names. The Mozilla Team also fixed a way of spoofing filenames in Firefox's 'What should Firefox do with this file' dialog boxes and a potential information leak about the existence of local filenames.
Impact
A remote attacker could craft a malicious NNTP link and entice a user to click it, potentially resulting in the execution of arbitrary code with the rights of the user running the browser. A local attacker could leverage the temporary file vulnerability to read the contents of another user's attachments or downloads. A remote attacker could also design a malicious web page that would allow to spoof filenames if the user uses the 'Open with...' function in Firefox, or retrieve information on the presence of specific files in the local filesystem.
