POP3: Outlook Address Spoofing
This signature detects multiple e-mail addresses in the FROM field of an e-mail message. Because Microsoft Outlook and Outlook Express display only the first e-mail address in the list, attackers can spoof the FROM e-mail address reported to the user.
Extended Description
Microsoft Outlook and Outlook Web Access clients are reported prone to a weakness that may allow remote attackers to send email with a spoofed address. It is reported that this issue arises when an attacker sends an e-mail by specifying multiple source email addresses. This issue may allow an attacker to carry out other attacks by combining this issue with social engineering and phishing attacks. An attacker may also bypass email gateways and send email to users.
