Het betreft hier een veiligheidslek in de mailclient, waardoor ongewenste personen bij je mail kunnen komen.
ICQ2000a has a small security flaw. It's not a major one, but it can become major.
It deals with using the ICQmailclient. ICQ creates a temporary link in your temp directory. This link contains your user ID and password encrypted. Even though your info is encrypted, it is useless. You can still access your ICQ mail via that temporary link just as you would go to any other URL stored on your computer.
This is bad if more than one person has access to your computer and knows about this. Also, if a person knows about this and you are infected with a trojan. Then they can simply download the link, then go to the link and change your password.
Fix: clear your temp directory after you log out of ICQ mail.
