CRITICAL:
Less critical

Privilege escalation

Local system

SOFTWARE:
FFTW 3.x
http://secunia.com/product/5504/

DESCRIPTION:
Javier Fernandez-Sanguino Pena has reported a vulnerability in FFTW,
which can be exploited by malicious, local users to perform certain
actions on a vulnerable system with escalated privileges.

The vulnerability is caused due to the temporary file
"/tmp/fftw-wisdom-to-conf$$" being created insecurely by
"/tools/fftw-wisdom-to-conf.in". This can be exploited via symlink
attacks to create or overwrite arbitrary files with the privileges of
the user running the affected application.

The vulnerability has been reported in version 3.0.1. Other versions
may also be affected.

SOLUTION:
Grant only trusted users access to affected systems.
