## Description:

This update for samba fixes the following issues:

Update to 4.22.5:

  * CVE-2025-10230: Command injection via WINS server hook script (bsc#1251280).
  * CVE-2025-9640: uninitialized memory disclosure via vfs_streams_xattr
    (bsc#1251279).

  * Relax samba-gpupdate requirement for cepces, certmonger, and sscep to a
    recommends. They are only required if utilizing certificate auto enrollment
    (bsc#1249087).

  * Disable timeouts for smb.service so that possibly slow running ExecStartPre
    script 'update-samba-security-profile' doesn't cause service start to fail
    due to timeouts (bsc#1249181).

  * Ensure semanage is pulled in as a requirement when samba in installed when
    selinux security access mechanism that is used (bsc#1249180).

  * don't attempt to label paths that don't exist, also remove unecessary
    evaluation of semange & restorecon cmds (bsc#1249179).

Update to 4.22.4:

  * netr_LogonSamLogonEx returns NR_STATUS_ACCESS_DENIED with SysvolReady=0
  * getpwuid does not shift to new DC when current DC is down
  * Windows security hardening locks out schannel'ed netlogon dc calls like
    netr_DsRGetDCName-
  * Unresponsive second DC can cause idmapping failure when using idmap_ad-
  * kinit command is failing with Missing cache Error.
  * Figuring out the DC name from IP address fails and breaks
    fork_domain_child().
  * vfs_streams_depot fstatat broken.
  * Delayed leader broadcast can block ctdb forever.
  * Apparently there is a conflict between shadow_copy2 module and virusfilter
    (action quarantine).
  * Fix handling of empty GPO link.
  * SMB ACL inheritance doesn't work for files created.

  * adjust gpgme build dependency for future-proofing
