CVE ID : CVE-2006-1753
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.

version 2.7.59-8
We recommend that you upgrade your fcheck package.
