Sophos Anti-Virus email virus may not be detected
|sophos-email-virus-undetected (15192)||Medium Risk|
Sophos Anti-Virus could allow a virus embedded in an email to pass undetected. If a qmail mail server employs the type of Delivery Status Notification (DSN) where the original email is not included in the bounce message, Sophos Anti-Virus engine may let the virus pass without detection. A remote attacker could send an email without any MIME boundary definitions to a qmail server that generates DSNs without including the original email in the bounce message to spread the virus.
Upgrade to the latest version of Sophos Anti-Virus for your operating system, available from the Sophos Web site. See References.
