security advisorymoderatebug fixScientific Linux SL7.x Advisory 2015:2184-7 Moderate: realmd Update
Moderate: realmd security, bug fix, and enhancement update. Date: Mon, 21 Dec 2015 23:16:31 +0000 Reply-To: scientific-linux-users@ Sender: Security Errata for Scientific Linux From: Pat Riehecky Subject: Security ERRATA Moderate: realmd on SL7.x x86_64 MIME-Version: 1.0 Message-ID: Synopsis: Moderate: realmd security, bug fix, and enhancement update Advisory ID: SLSA-2015:2184-7 Issue Date: 2015-11-19 CVE Numbers: CVE-2015-2704 -- A flaw was found in the way realmd parsed certain input when writing configuration into the sssd.conf or smb.conf file. A remote attacker could use this flaw to inject arbitrary configurations into these files via a newline character in an LDAP response. (CVE-2015-2704) It was found that the realm client would try to automatically join an active directory domain without authentication, which could potentially lead to privilege escalation within a specified domain. The realmd packages have been upgraded to upstream version 0.16.1, which provides a number of bug fixes and enhancements over the previous version. This update also fixes the following bugs: * Joining a Scientific Linux machine to a domain using the realm utility creates /home/domainname/[username]/ directories for domain users. Previously, SELinux labeled the domain users' directories incorrectly. As a consequence, the domain users sometimes experienced problems with SELinux policy. This update modifies the realmd service default behavior so that the domain users' directories are compatible with the standard SELinux policy. * Previously, the realm utility was unable to join or discover domains with domain names containing underscore (_). The realmd service has been modified to process underscores in domain names correctly, which fixes the described bug. In addition, this update adds the following enhancement: * The realmd utility now allows the user to disable automatic ID mapping from the command line. To disable the mapping, pass the "--automatic-id- mapping=no" option to the realmd utility. -- SL7 x86_64 realmd-0.16.1-5.el7.x86_64.rpm realmd-debuginfo-0.16.1-5.el7.x86_64.rpm realmd-devel-docs-0.16.1-5.el7.x86_64.rpm - Scientific Linux Development Team .

Summary: Updated realmd packages that fix two security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: The realmd DBus system service manages discovery of and enrollment in realms and domains, such as Active Directory or Identity Management (IdM). The realmd service detects available domains, automatically configures the system, and joins itas an account to a domain. A flaw was found in the way realmd parsed certain input when writing configuration into the sssd.conf or smb.conf file. A remote attacker could use this flaw to inject arbitrary configurations into these files via a newline character in an LDAP response. (CVE-2015-2704) It was found that the realm client would try to automatically join an active directory domain without authentication, which could potentially lead to privilege escalation within a specified domain. (BZ#1205751) The realmd packages have been upgraded to upstream version 0.16.1, which provides a number of bug fixes and enhancements over the previous version. (BZ#1174911) This update also fixes the following bugs: * Joining a Red Hat Enterprise Linux machine to a domain using the realm utility creates /home/domainname/[username]/ directories for domain users. Previously, SELinux labeled the domain users' directories incorrectly. As a consequence, the domain users sometimes experienced problems with SELinux policy. This update modifies the realmd service default behavior so that the domain users' directories are compatible with the standard SELinux policy. (BZ#1241832) * Previously, the realm utility was unable to join or discover domains with domain names containing underscore (_). The realmd service has been modified to process underscores in domain names correctly, which fixes the described bug. (BZ#1243771) In addition, this update adds the following enhancement: * The realmd utility now allows the user to disable automatic ID mapping from the command line. To disable the mapping, pass the "--automatic-id-mapping=no" option to the realmd utility. (BZ#1230941) All realmd users are advised to upgrade to these updated packages, which correct these issues and add these enhancements. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5.
