The remote host is missing an update to fcheck announced via advisory DSA 1035-1. Steve Kemp from the Debian Security Audit project discovered that a cronjob contained in fcheck, a file integrity checker, creates a temporary file in an insecure fashion. The old stable distribution (woody) is not affected by this problem.
For the stable distribution (sarge) this problem has been fixed in version 2.7.59-7sarge1. For the unstable distribution (sid) this problem has been fixed in version 2.7.59-8 We recommend that you upgrade your fcheck package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201035-1
