Description

Javier Fernandez-Sanguino Pena discovered insecure temporary file use in cfengine2, a tool for configuring and maintaining networked machines, that can be exploited by a symlink attack to overwrite arbitrary files owned by the user executing cfengine, which is probably root.

The oldstable distribution (woody) is not affected by this problem.
