[slackware-security]  samba (SSA:2023-216-02)

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-4.18.5-i586-1_slack15.0.txz:  Upgraded.
  PLEASE NOTE: We are taking the unusual step of moving to the latest Samba
  branch because Windows has made changes that break Samba 4.15.x. The last
  4.15.x will be retained in /pasture as a fallback. There may be some
  required configuration changes with this, but we've kept using MIT Kerberos
  to try to have the behavior change as little as possible. Upgrade carefully.
  This update fixes security issues:
  When winbind is used for NTLM authentication, a maliciously crafted request
  can trigger an out-of-bounds read in winbind and possibly crash it.
  SMB2 packet signing is not enforced if an admin configured
  "server signing = required" or for SMB2 connections to Domain Controllers
  where SMB2 packet signing is mandatory.
  An infinite loop bug in Samba's mdssvc RPC service for Spotlight can be
  triggered by an unauthenticated attacker by issuing a malformed RPC request.
  Missing type validation in Samba's mdssvc RPC service for Spotlight can be
  used by an unauthenticated attacker to trigger a process crash in a shared
  RPC mdssvc worker process.
  As part of the Spotlight protocol Samba discloses the server-side absolute
  path of shares and files and directories in search results.
