New samba packages are available for Slackware 14.0, 14.1, 14.2, and -current to
fix security issues.

Here are the details from the Slackware 14.2 ChangeLog:

patches/packages/samba-4.4.5-i586-1_slack14.2.txz: Upgraded.
This release fixes a security issue:
Client side SMB2/3 required signing can be downgraded.
It’s possible for an attacker to downgrade the required signing for an
SMB2/3 client connection, by injecting the SMB2_SESSION_FLAG_IS_GUEST or
SMB2_SESSION_FLAG_IS_NULL flags. This means that the attacker can
impersonate a server being connected to by Samba, and return malicious
results.
For more information, see:

(* Security fix *)

Where to find the new packages:
