Debian Security Advisory DSA 661-1 security@debian.org
http://www.debian.org/security/ Martin Schulze

---------------------------------------------------------------------------

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.
