Dan McMahill noticed that our advisory DSA 661-1 did not correct the multiple insecure files problem, hence, this update. For completeness below is the original advisory text :
Javier Fernandez-Sanguino Pena 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 :
- CAN-2005-0017 Multiple insecure temporary files in the f2c translator.
- CAN-2005-0018
Two insecure temporary files in the f2 shell script.
