    Vulnerability  : insecure temporary files
    Problem-Type   : local

    CVE ID         : CAN-2005-0017 CAN-2005-0018
    
    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:
    
    CAN-2005-0017
    
        Multiple insecure temporary files in the f2c translator.
    
    CAN-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.
