New bash packages are available for Slackware 13.1, 13.37, 14.0, 14.1, and 14.2
to fix security issues.
Here are the details from the Slackware 14.2 ChangeLog:
patches/packages/bash-4.3.048-i586-1_slack14.2.txz: Upgraded.
This update fixes two security issues found in bash before 4.4:
The expansion of ‘\h’ in the prompt string allows remote authenticated users
to execute arbitrary code via shell metacharacters placed in ‘hostname’ of a
machine. The theoretical attack vector is a hostile DHCP server providing a
crafted hostname, but this is unlikely to occur in a normal Slackware
configuration as we ignore the hostname provided by DHCP.
Specially crafted SHELLOPTS+PS4 environment variables used against bogus
setuid binaries using system()/popen() allowed local attackers to execute
arbitrary code as root.
For more information, see:

https://vulners.com/cve/CVE-2016-7543
(* Security fix *)
