CVE-2002-0285
HighSummary
Outlook Express 5.5 and 6.0 on Windows treats a carriage return ('CR') in a message header as a valid carriage return/line feed combination (CR/LF). This could allow remote attackers to bypass virus protection and other filtering mechanisms via a mail message with headers that only contain the CR, causing Outlook to create separate headers.
Risk Assessment
Organizations may be vulnerable to attacks that bypass virus and filtering protections, potentially leading to malware infections or data breaches.
Recommendation
It is recommended to update Outlook Express to the latest version and implement additional filtering mechanisms that can detect and block such unusual headers.
