New expat packages are available for Slackware 14.0, 14.1, 14.2, and -current
to fix a security issue.

Here are the details from the Slackware 14.2 ChangeLog:

patches/packages/expat-2.4.1-i586-1_slack14.2.txz: Upgraded.
This update provides new mitigations against the “billion laughs” denial
of service attack.
