The remote host is missing an update to xmail announced via advisory DSA 902-1. A buffer overflow has been discovered in the sendmail program of xmail, an advanced, fast and reliable ESMTP/POP3 mail server that could lead to the execution of arbitrary code with group mail privileges. The old stable distribution (woody) does not contain xmail packages.

For the stable distribution (sarge) this problem has been fixed in version 1.21-3sarge1. For the unstable distribution (sid) this problem has been fixed in version 1.22-1. We recommend that you upgrade your xmail package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20902-1
