A vulnerability in the mail handling service in some versions of Microsoft Windows could allow a remote attacker to compromise the affected system.
The Simple Mail Transfer Protocol (SMTP) is the most common protocol for the delivery of electronic mail between systems on the Internet. Some versions of Microsoft Windows support the ability to act as an SMTP server. The ability to interact with the Domain Name System (DNS) is critical for an SMTP server to deliver mail to a remote user (e.g., [email protected]
). A buffer management flaw exists in the way that the SMTP service handles DNS responses. A remote attacker with the ability to craft DNS response messages could exploit this vulnerability to compromise the affected system.
A remote, unauthenticated attacker may be able to execute arbitrary code with administrative privileges on an affected system.
