Detail
Problem Description: Updated openswan packages that fix various security issues are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 3. Description: Openswan is a free implementation of Internet Protocol Security (IPsec) and Internet Key Exchange (IKE). IPsec uses strong cryptography to provide both authentication and encryption services. These services allow you to build secure tunnels through untrusted networks. Everything passing through the untrusted network is encrypted by the IPsec gateway machine, and decrypted by the gateway at the other end of the tunnel. The resulting tunnel is a virtual private network (VPN). Gerd v. Egidy discovered a flaw in the Dead Peer Detection (DPD) in Openswan's pluto IKE daemon. A remote attacker could use a malicious DPD packet to crash the pluto daemon. (CVE-2009-0790) It was discovered that Openswan's livetest script created temporary files in an insecure manner. A local attacker could use this flaw to overwrite arbitrary files owned by the user running the script. (CVE-2008-4190) Note: The livetest script is an incomplete feature and was not automatically executed by any other script distributed with Openswan, or intended to be used at all, as was documented in its man page. In these updated packages, the script only prints an informative message and exits immediately when run. All users of openswan are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the ipsec service will be restarted automatically. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 460425 - CVE-2008-4190 openswan: Insecure auxiliary /tmp file usage (symlink attack possible) 491895 - CVE-2009-0790 openswan: ISAKMP DPD remote DoS |
