New f2c packages are available for Debian GNU/Linux

---------------------------------------------------------------------------
Debian Security Advisory DSA 661-2 security@debian.org
http://www.debian.org/security/ Martin Schulze
April 20th, 2005 http://www.debian.org/security/faq
---------------------------------------------------------------------------

Package : f2c
Vulnerability : insecure temporary files
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2005-0017

Dan McMahill noticed that our 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 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.

For the stable distribution (woody) and all others including testing this problem has been fixed in version 20010821-3.2.

We recommend that you upgrade your f2c package.
