Errata
======
The previous version of the X.Org X server (1.3.0.0-r4) did not
properly address the integer overflow vulnerability in the MIT-SHM
extension (CVE-2007-6429). It failed to check on Pixmaps of certain
bit depths.
All users of the X.Org X server package should upgrade to
x11-base/xorg-server-1.3.0.0-r5.
The corrected sections appear below.
