DESCRIPTION:
Secunia Research has discovered two vulnerabilities in MailEnable,
which can be exploited by malicious people to cause a DoS (Denial of
Service).

1) An insufficient length check when appending data to a predefined
log message into a buffer using strcat_s() may result in an unhandled
invalid parameter error. This can be exploited to crash the SMTP
service (MESMTPC.exe) via an overly long email address in the "MAIL
FROM" command.

2) An insufficient length check when copying data with a predefined
log message into a buffer using strcpy_s() may result in an unhandled
invalid parameter error. This can be exploited to crash the SMTP
service (MESMTPC.exe) via an overly long domain name in the "RCPT TO"
command.

The vulnerabilities are confirmed in version 4.25 of Standard,
Professional, and Enterprise editions. Other versions may also be
affected.

SOLUTION:
Apply hotfix ME-10044 or update to version 4.26.

PROVIDED AND/OR DISCOVERED BY:
Dmitriy Pletnev, Secunia Research.
