-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Low: krb5 security, bug fix, and enhancement update Advisory ID: RHSA-2018:3071-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2018:3071 Issue date: 2018-10-30 CVE Names: CVE-2018-5729 CVE-2018-5730 ===================================================================== 1. Summary: An update for krb5 is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Low. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) 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) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server (v. 7) - aarch64, ppc64le, s390x 3. Description: Kerberos is a network authentication system, which can improve the security of your network by eliminating the insecure practice of sending passwords over the network in unencrypted form. It allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos key distribution center (KDC). Security Fix(es): * krb5: null dereference in kadmind or DN container check bypass by supplying special crafted data (CVE-2018-5729) * krb5: DN container check bypass by supplying special crafted data (CVE-2018-5730) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.6 Release Notes linked from the References section. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing the updated packages, running Kerberos services (krb5kdc, kadmin, and kprop) will be restarted automatically. 5. Bugs fixed (https://bugzilla.redhat.com/): 1373909 - Running systemctl stop kadmin.service causes the status to be failed instead of inactive 1497301 - [RFE] Add German translation (de_DE.UTF-8) 1525232 - Fix network service dependencies 1538491 - certid option of PKINIT plugin does not handle leading zeros 1539824 - Order of processing for files in included directories is undefined 1540130 - [RFE] make preauth types more descriptive in krb5 trace 1551082 - CVE-2018-5730 krb5: DN container check bypass by supplying special crafted data 1551083 - CVE-2018-5729 krb5: null dereference in kadmind or DN container check bypass by supplying special crafted data 1563166 - kdestroy -A does not work with multiple principals when using KCM 1570600 - krb5-libs uses slow crypto implementation 1599721 - ipa-server-install fails when FIPS mode is enabled 6.
