The remote host is missing an update to gsambad announced via advisory DSA 1327-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201327-1

Steve Kemp from the Debian Security Audit project discovered that gsambad, a GTK+ configuration tool for samba, uses temporary files in an unsafe manner which may be exploited to truncate arbitary files from the local system. For the stable distribution (etch) this problem has been fixed in version 0.1.4-2etch1. For the unstable distribution (sid) this problem will be fixed shortly. We recommend that you upgrade your gsambad package.
