[slackware-security]  samba (SSA:2023-284-03)

New samba packages are available for Slackware 15.0 and -current to
fix security issues.


Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/samba-4.18.8-i586-1_slack15.0.txz:  Upgraded.
  This is a security release in order to address the following defects:
  Unsanitized pipe names allow SMB clients to connect as root to existing
  unix domain sockets on the file system.
  SMB client can truncate files to 0 bytes by opening files with OVERWRITE
  disposition when using the acl_xattr Samba VFS module with the smb.conf
  setting "acl_xattr:ignore system acls = yes"
  An RODC and a user with the GET_CHANGES right can view all attributes,
  including secrets and passwords. Additionally, the access check fails
  open on error conditions.
  Calls to the rpcecho server on the AD DC can request that the server block
  for a user-defined amount of time, denying service.
  Samba can be made to start multiple incompatible RPC listeners, disrupting
  service on the AD DC.
