The remote host is vulnerable to a remote 'format string' flaw.
The remote host is using DtMail, a mail user agent included in CDE, the default desktop environment for Sun Solaris. It is reported that versions of DtMail shipped with Solaris 8 and 9 are prone to a local format string issue. An local attacker may exploit this vulnerability to execute malicious code with mail group privileges.
Upgrade or patch according to vendor recommendations.
