GLSA-200501-43 : f2c: Insecure temporary file creation

This script is Copyright (C) 2005-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200501-43
(f2c: Insecure temporary file creation)

Javier Fernandez-Sanguino Pena from the Debian Security Audit Team
discovered that f2c creates temporary files in world-writeable
directories with predictable names.

Impact :

A local attacker could create symbolic links in the temporary
files directory, pointing to a valid file somewhere on the filesystem.
When f2c is executed, this would result in the file being overwritten
with the rights of the user running the software, which could be the
root user.

Workaround :

There is no known workaround at this time.

Solution :

All f2c users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=dev-lang/f2c-20030320-r1'

Risk factor :

Low / CVSS Base Score : 2.1
