Detail
Problem Description: Updated samba4 packages that fix one security issue, multiple bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 3. Description: Samba is an open-source implementation of the Server Message Block (SMB) or Common Internet File System (CIFS) protocol, which allows PC-compatible machines to share files, printers, and other information. A flaw was found in the Samba suite's Perl-based DCE/RPC IDL (PIDL) compiler, used to generate code to handle RPC calls. This could result in code generated by the PIDL compiler to not sufficiently protect against buffer overflows. (CVE-2012-1182) The samba4 packages have been upgraded to upstream version 4.0.0, which provides a number of bug fixes and enhancements over the previous version. In particular, improved interoperability with Active Directory (AD) domains. SSSD now uses the libndr-krb5pac library to parse the Privilege Attribute Certificate (PAC) issued by an AD Key Distribution Center (KDC). The Cross Realm Kerberos Trust functionality provided by Identity Management, which relies on the capabilities of the samba4 client library, is included as a Technology Preview. This functionality and server libraries, is included as a Technology Preview. This functionality uses the libndr-nbt library to prepare Connection-less Lightweight Directory Access Protocol (CLDAP) messages. Additionally, various improvements have been made to the Local Security Authority (LSA) and Net Logon services to allow verification of trust from a Windows system. Because the Cross Realm Kerberos Trust functionality is considered a Technology Preview, selected samba4 components are considered to be a Technology Preview. For more information on which Samba packages are considered a Technology Preview, refer to Table 5.1, "Samba4 Package Support" in the Release Notes, linked to from the References. (BZ#766333, BZ#882188) This update also fixes the following bug: * Prior to this update, if the Active Directory (AD) server was rebooted, Winbind sometimes failed to reconnect when requested by "wbinfo -n" or "wbinfo -s" commands. Consequently, looking up users using the wbinfo tool failed. This update applies upstream patches to fix this problem and now looking up a Security Identifier (SID) for a username, or a username for a given SID, works as expected after a domain controller is rebooted. (BZ#878564) All users of samba4 are advised to upgrade to these updated packages, which fix these issues and add these enhancements. Warning: If you upgrade from Red Hat Enterprise Linux 6.3 to Red Hat Enterprise Linux 6.4 and you have Samba in use, you should make sure that you uninstall the package named "samba4" to avoid conflicts during the upgrade. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5. Bugs fixed (http://bugzilla.redhat.com/): 766333 - Rebase Samba4 libraries to pick up functionality required for IdM 804093 - CVE-2012-1182 samba: Multiple heap-based buffer overflows in memory management based on NDR marshalling code output 861892 - samba4's wbclient/smbclient provides need to be filtered to avoid confusion with samba's wbclient/smbclient provides 864889 - Configure winbind_krb5_locator.so via alternatives to allow IPA AD trusts use 867317 - pam_winbind.conf is not packaged in samba-winbind-clients where the module is packaged. 867854 - auth_builtin auth_domain auth_sam and auth_winbind are built as shared modules. 868248 - samba-winbind package wants /var/log/samba 868419 - samba4 smb and winbind init scripts missing export KRB5CCNAME 877085 - Wrong sysconfig filename 878564 - IPA trust cannot always lookup AD users with wbinfo 882188 - samba4-libs: yyin symbol collision 885089 - Samba netlogon AES support incorrect 886157 - samba4 should use the same winbind pipes as samba 895718 - Incomplete rpm provides filters causes issues with the samba4-libs package on certain architectures |
