[slackware-security] libX11 (SSA:2021-139-01)
New libX11 packages are available for Slackware 14.0, 14.1, 14.2, and -current

Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/libX11-1.7.1-i586-1_slack14.2.txz: Upgraded.
This update fixes missing request length checks in libX11 that can lead to
the emission of extra X protocol requests to the X server.
