[slackware-security] xorg-server (SSA:2017-279-03)

New xorg-server packages are available for Slackware 14.0, 14.1, 14.2,
and -current to fix security issues.


Here are the details from the Slackware 14.2 ChangeLog:
+--------------------------+
patches/packages/xorg-server-1.18.3-i586-4_slack14.2.txz: Rebuilt.
This update fixes two security issues:
Xext/shm: Validate shmseg resource id, otherwise it can belong to a
non-existing client and abort X server with FatalError "client not
in use", or overwrite existing segment of another existing client.
Generating strings for XKB data used a single shared static buffer,
which offered several opportunities for errors. Use a ring of
resizable buffers instead, to avoid problems when strings end up
longer than anticipated.
For more information, see:
