Package : cfengine
Vulnerability : insecure temporary files
Problem type : local
Debian-specific: no
CVE ID : CAN-2005-2960

Javier Fernández-Sanguino Peña discovered several insecure temporary
file uses in cfengine, 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.

For the old stable distribution (woody) these problems have been fixed in
version 1.6.3-9woody1.

For the stable distribution (sarge) these problems have been fixed in
version 1.6.5-1sarge1.

For the unstable distribution (sid) these problems have will be fixed soon.

We recommend that you upgrade your cfengine package.
