Debian Security Advisory DSA 661-1                     security@debian.org

Package        : f2c
Vulnerability  : insecure temporary files
Problem-Type   : local
Debian-specific: no
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.
