The remote host is missing an update to f2c announced via advisory DSA 661-1.

Javier Fernández-Sanguino Peña from the Debian Security Audit project discovered that f2c and fc, which are both part of the f2c package, a fortran 77 to C/C++ translator, open temporary files insecurely and are hence vulnerable to a symlink attack. The Common Vulnerabilities and Exposures project identifies the following vulnerabilities: CVE-2005-0017 Multiple insecure temporary files in the f2c translator. CVE-2005-0018 Two insecure temporary files in the f2 shell script. For the stable distribution (woody) these problems have been fixed in version 20010821-3.1 For the unstable distribution (sid) these problems will be fixed soon. We recommend that you upgrade your f2c package.
