New gnupg2 packages are available for Slackware 13.37, 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/gnupg2-2.0.31-i586-1_slack14.2.txz: Upgraded.
Sanitize the diagnostic output of the original file name in verbose mode.
By using a made up file name in the message it was possible to fake status
messages. Using this technique it was for example possible to fake the
verification status of a signed mail.
