Multiple buffer overflows in Mozilla POP3 protocol handler

Vulnerability Note VU#125776

Original Release Date: 2004-09-17 | Last Revised: 2004-09-17

Overview

There are multiple buffer overflow vulnerabilities in the Mozilla POP3 protocol handler that could allow a remote attacker to execute arbitrary code.

Description

Post Office Protocol Version 3 (POP3) is a mail protocol that provides a means for retrieving email from a remote server. The Mozilla mail client supports the POP3 protocol. There are multiple vulnerabilities in a number of functions used by the Mozilla POP3 protocol handler. The vulnerable functions include: FreeMsgInfo(), GetXtndXlstMsgid(), GetUidlList(), and GetList(). When processing POP3 responses, a specially crafted response could trigger a buffer overflow condition.

Impact

By sending a specially crafted POP3 response to an affected client, a remote attacker could cause the client to crash or potentially execute arbitrary code. Exploitation of this vulnerability would require a user to connect to a malicious POP3 server.
