Message: There has been a new vulnerability discovered in certain versions of Eudora, a popular email client, that can lead to system compromise through specially crafted URLs in the body of a message. For more information, check out the vulnerability at http://secunia.com/advisories/11568/. In general, the following practices should be followed:
Never open attachments that you weren't expecting without at least verifying they were legitimate. This includes links to web-sites or other types of attached documents. The verification can involve either e-mailing back the sender and asking, calling the sender, or some other means of verification. In the case of anything claiming to be from email@example.com or something similar, you can always call the ITS Center at 5-2000.
Always keep your system up-to-date with patches. The various software makers usually keep a web-site up for their customers to update software. Microsoft's main site is at http://windowsupdate.microsoft.com.
