TITLE:
Microsoft Exchange / Windows SMTP Service Two Vulnerabilities

Moderately critical
Impact: Exposure of sensitive information, DoS
Where: From remote

VERIFY ADVISORY:
http://secunia.com/advisories/39376/

DESCRIPTION:
Some vulnerabilities have been reported in Microsoft Windows and
Exchange Server, which can be exploited by malicious people to cause
a DoS (Denial of Service) or gain knowledge of sensitive
information.

1) An error in the SMTP service when parsing DNS Mail Exchanger (MX)
records can be exploited to cause the service to stop responding
until a specially crafted message is removed from the queue and the
service is restarted.

2) A memory allocation error in the SMTP component when interpreting
SMTP responses can be exploited to disclose random e-mail message
fragments by sending invalid commands followed by the STARTTLS
command.

SOLUTION:
Apply patches.
