Created 389-ds-base tracking bugs for this issue: Affects: fedora-all [bug 1592226] *** Bug 1591481 has been marked as a duplicate of this bug. *** External References: https://pagure.io/389-ds-base/issue/49789 Mitigation: On 389-ds-base 1.3.1 and above: 1- Deactivate clear password storing by default, to prevent new passwords to be logged. -> in cn=config, set nsslapd-unhashed-pw-switch attribute to 'off' or 'nolog' 2- Trim changelog to ensure currently stored passwords are removed. For Replication: -> in cn=changelog5,cn=config, reduce nsslapd-changelogmaxentries, nsslapd-changelogtrim-interval and nsslapd-changelogmaxage -> force a replication & wait for the changelogtrim-interval time -> restore previous values For RetroChangelog: -> deactivate the plugin -> restart directory server -> reactivate the plugin -> restart directory server This issue has been addressed in the following products: Red Hat Enterprise Linux 8 Via RHSA-2019:3401 https://access.redhat.com/errata/RHSA-2019:3401 This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2018-10871 |
