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

Here are the details from the Slackware 15.0 ChangeLog:

patches/packages/samba-4.15.11-i586-1_slack15.0.txz: Upgraded.
This update fixes the following security issue:
There is a limited write heap buffer overflow in the GSSAPI unwrap_des()
and unwrap_des3() routines of Heimdal (included in Samba).
For more information, see:
