FreeBSD-SA-01:27 Security Advisory FreeBSD, Inc. Topic: cfengine port contains remote root vulnerability Category: ports Module: cfengine Announced: 2001-03-12 Credits: Pekka Savola <pekkas@NETCORE.FI.> Affects: Ports collection prior to the correction date. Corrected: 2001-01-21 Vendor status: Updated version released FreeBSD only: NO I. Background cfengine is a system for automating the configuration and maintenance of large networks. II. Problem Description The cfengine port, versions prior to 1.6.1, contained several format string vulnerabilities which allow a remote attacker to execute arbitrary code on the local system as the user running cfengine, usually user root. The cfengine port is not installed by default, nor is it "part of FreeBSD" as such: it is part of the FreeBSD ports collection, which contains nearly 4700 third-party applications in a ready-to-install format. The ports collections shipped with FreeBSD 3.5.1 and 4.2 contain this problem since it was discovered after the releases. FreeBSD makes no claim about the security of these third-party applications, although an effort is underway to provide a security audit of the most security-critical ports. III. Impact Arbitrary remote users can execute code on the local system as the user running cfengine, usually user root. If you have not chosen to install the cfengine port/package, then your system is not vulnerable to this problem. IV. Workaround One of the following: 1) Deinstall the cfengine port/package, if you have installed it. 2) Implement access controls on connections to the cfengine server, either at the application level using the cfengine configuration file, or by using network-level packet filtering on the local system using ipfw(8)/ipf(8), or on the perimeter firewalls. V. Solution One of the following: 1) Upgrade your entire ports collection and rebuild the cfengine port. 2) Deinstall the old package and install a new package dated after the correction date, obtained from: [i386] ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/sysutils/cfengine-1.6.3.tar.gz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/sysutils/cfengine-1.6.3.tar.gz [alpha] Packages are not automatically generated for the alpha architecture at this time due to lack of build resources. 3) download a new port skeleton for the cfengine port from: http://www.freebsd.org/ports/ and use it to rebuild the port. 4) Use the portcheckout utility to automate option (3) above. The portcheckout port is available in /usr/ports/devel/portcheckout or the package can be obtained from: ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/devel/portcheckout-2.0.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-4-stable/devel/portcheckout-2.0.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5-current/devel/portcheckout-2.0.tgz ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/alpha/packages-5-current/devel/portcheckout-2.0.tgz -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.4 (FreeBSD) Comment: For info see http://www.gnupg.org iQCVAwUBOq1dclUuHi5z0oilAQFhhAQApfRMj88GYMKiTtLeyjWeaDLFIlDjUTl4 fF1QQNzetOSIoVjA+CsbkTgsX/c8B6Lc7BuTI7K3BLKUu2QC2GbYkn5/ymCdYQeE dW2S00bMdBP6GwURAdFnizezkZq5Y3oEVYXVL4s91M9jb3wCwNOwnbfKH/aegFvL ZOjDvMUdjb0= =yzjS -----END PGP SIGNATURE-----
