Synopsis: Important: ipa-client security update Issue Date: 2013-01-23 CVE Numbers: CVE-2012-5484 -- A weakness was found in the way IPA clients communicated with IPA servers when initially attempting to join IPA domains. As there was no secure way to provide the IPA server's Certificate Authority (CA) certificate to the client during a join, the IPA client enrollment process was susceptible to man-in-the-middle attacks. This flaw could allow an attacker to obtain access to the IPA server using the credentials provided by an IPA client, including administrative access to the entire domain if the join was performed using an administrator's credentials. (CVE-2012-5484) Note: This weakness was only exposed during the initial client join to the realm, because the IPA client did not yet have the CA certificate of the server. Once an IPA client has joined the realm and has obtained the CA certificate of the IPA server, all further communication is secure. If a client were using the OTP (one-time password) method to join to the realm, an attacker could only obtain unprivileged access to the server (enough to only join the realm). When a fix for this flaw has been applied to the client but not yet the server, ipa-client-install, in unattended mode, will fail if you do not have the correct CA certificate locally, noting that you must use the "--force" option to insecurely obtain the certificate. In interactive mode, the certificate will try to be obtained securely from LDAP. If this fails, you will be prompted to insecurely download the certificate via HTTP. In the same situation when using OTP, LDAP will not be queried and you will be prompted to insecurely download the certificate via HTTP. -- SL5 x86_64 ipa-client-2.1.3-5.el5_9.2.x86_64.rpm ipa-client-debuginfo-2.1.3-5.el5_9.2.x86_64.rpm i386 ipa-client-2.1.3-5.el5_9.2.i386.rpm ipa-client-debuginfo-2.1.3-5.el5_9.2.i386.rpm For dependency resolution the following packages have been added to the SL5 security repo on some older releases: x86_64 authconfig-5.3.21-7.el5.x86_64.rpm authconfig-gtk-5.3.21-7.el5.x86_64.rpm certmonger-0.50-3.el5.x86_64.rpm curl-7.15.5-15.el5.i386.rpm curl-7.15.5-15.el5.x86_64.rpm curl-devel-7.15.5-15.el5.i386.rpm curl-devel-7.15.5-15.el5.x86_64.rpm libipa_hbac-1.5.1-58.el5.i386.rpm libipa_hbac-1.5.1-58.el5.x86_64.rpm libipa_hbac-devel-1.5.1-58.el5.i386.rpm libipa_hbac-devel-1.5.1-58.el5.x86_64.rpm libipa_hbac-python-1.5.1-58.el5.x86_64.rpm libtdb-1.2.10-1.el5.i386.rpm libtdb-1.2.10-1.el5.x86_64.rpm libtdb-devel-1.2.10-1.el5.i386.rpm libtdb-devel-1.2.10-1.el5.x86_64.rpm policycoreutils-1.33.12-14.8.el5.x86_64.rpm policycoreutils-gui-1.33.12-14.8.el5.x86_64.rpm policycoreutils-newrole-1.33.12-14.8.el5.x86_64.rpm shadow-utils-4.0.17-21.el5.x86_64.rpm sssd-1.5.1-58.el5.x86_64.rpm sssd-client-1.5.1-58.el5.i386.rpm sssd-client-1.5.1-58.el5.x86_64.rpm sssd-tools-1.5.1-58.el5.x86_64.rpm xmlrpc-c-1.16.24-1206.1840.4.el5.i386.rpm xmlrpc-c-1.16.24-1206.1840.4.el5.x86_64.rpm xmlrpc-c-apps-1.16.24-1206.1840.4.el5.x86_64.rpm xmlrpc-c-c++-1.16.24-1206.1840.4.el5.i386.rpm xmlrpc-c-c++-1.16.24-1206.1840.4.el5.x86_64.rpm xmlrpc-c-client-1.16.24-1206.1840.4.el5.i386.rpm xmlrpc-c-client++-1.16.24-1206.1840.4.el5.i386.rpm xmlrpc-c-client-1.16.24-1206.1840.4.el5.x86_64.rpm xmlrpc-c-client++-1.16.24-1206.1840.4.el5.x86_64.rpm xmlrpc-c-devel-1.16.24-1206.1840.4.el5.i386.rpm xmlrpc-c-devel-1.16.24-1206.1840.4.el5.x86_64.rpm i386 authconfig-5.3.21-7.el5.i386.rpm authconfig-gtk-5.3.21-7.el5.i386.rpm certmonger-0.50-3.el5.i386.rpm curl-7.15.5-15.el5.i386.rpm curl-devel-7.15.5-15.el5.i386.rpm libipa_hbac-1.5.1-58.el5.i386.rpm libipa_hbac-devel-1.5.1-58.el5.i386.rpm libipa_hbac-python-1.5.1-58.el5.i386.rpm libtdb-1.2.10-1.el5.i386.rpm libtdb-devel-1.2.10-1.el5.i386.rpm policycoreutils-1.33.12-14.8.el5.i386.rpm policycoreutils-gui-1.33.12-14.8.el5.i386.rpm policycoreutils-newrole-1.33.12-14.8.el5.i386.rpm shadow-utils-4.0.17-21.el5.i386.rpm sssd-1.5.1-58.el5.i386.rpm sssd-client-1.5.1-58.el5.i386.rpm sssd-tools-1.5.1-58.el5.i386.rpm xmlrpc-c-1.16.24-1206.1840.4.el5.i386.rpm xmlrpc-c-apps-1.16.24-1206.1840.4.el5.i386.rpm xmlrpc-c-c++-1.16.24-1206.1840.4.el5.i386.rpm xmlrpc-c-client-1.16.24-1206.1840.4.el5.i386.rpm xmlrpc-c-client++-1.16.24-1206.1840.4.el5.i386.rpm xmlrpc-c-devel-1.16.24-1206.1840.4.el5.i386.rpm - Scientific Linux Development Team
