==================================================================== Red Hat Security Advisory Synopsis: Important: openswan security update Advisory ID: RHSA-2009:1138-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1138.html Issue date: 2009-07-02 CVE Names: CVE-2009-2185 ==================================================================== 1. Summary: Updated openswan packages that fix multiple 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 Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, 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). Multiple insufficient input validation flaws were found in the way Openswan's pluto IKE daemon processed some fields of X.509 certificates. A remote attacker could provide a specially-crafted X.509 certificate that would crash the pluto daemon. (CVE-2009-2185) All users of openswan are advised to upgrade to these updated packages, which contain a backported patch 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 5. Bugs fixed (http://bugzilla.redhat.com/): 507362 - CVE-2009-2185 Openswan ASN.1 parser vulnerability 6.
