Here are the details from the Slackware 15.0 ChangeLog:
+--------------------------+
patches/packages/util-linux-2.37.4-i586-1_slack15.0.txz: Upgraded.
 This release fixes a security issue in chsh(1) and chfn(8):
 By default, these utilities had been linked with libreadline, which allows
 the INPUTRC environment variable to be abused to produce an error message
 containing data from an arbitrary file. So, don't link these utilities with
 libreadline as it does not use secure_getenv() (or a similar concept), or
 sanitize the config file path to avoid vulnerabilities that could occur in
 set-user-ID or set-group-ID programs.
 For more information, see:

 (* Security fix *)
