-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
Upstream has opened two bugs for issues in realmd
This initial response has a CVE ID only for the second one.
could lead to remote attackers logging into the local system by placing an evil AD server in the LAN https://bugs.freedesktop.org/show_bug.cgi?id=89205
Is upstream planning to announce this as a vulnerability fix? Although the old behavior was unsafe if there was any possibility of an untrusted device on the LAN, it appears that the old behavior had been intentional. For example, the old behavior may have been chosen as a security/convenience tradeoff. This example might be applicable: https://fedoraproject.org/wiki/QA:Testcase_realmd_join_automatic
could lead to remote attackers logging into the local system by offering \r in LDAP responses that are treated by sssd and winbind as newline separator; therefore allowing to smuggle options into the config files used for startup
https://bugs.freedesktop.org/show_bug.cgi?id=89207
No data that was retrieved before join ... should be used when configuring sssd.conf and/or smb.conf.
