Denial of Service in Mozilla and Netscape Mail Clients

CVE-2002-2338

Summary

The POP3 mail clients in Mozilla versions up to 1.0 and Netscape Communicator versions up to 4.7 are susceptible to a Denial of Service vulnerability. An attacker can exploit this issue by sending a specially crafted email message that contains a dot (.) at a newline. This formatting leads the mail client to incorrectly interpret the end of the message, preventing users from receiving new emails. This vulnerability not only disrupts service but can also render the mail client unusable until addressed. Users of these obsolete versions are strongly advised to upgrade to ensure their email communications remain secure.
