[Updated 22th January 2008]
The original packages distributed with this errata had a bug which could
cause some X applications to fail on 32-bit platforms. We have updated the
packages to correct this bug.

Two integer overflow flaws were found in the X.Org server's EVI and MIT-SHM
modules. A malicious authorized client could exploit these issues to cause
a denial of service (crash), or potentially execute arbitrary code with
root privileges on the X.Org server. (CVE-2007-6429)

A memory corruption flaw was found in the X.Org server's XInput extension.
A malicious authorized client could exploit this issue to cause a denial of
service (crash), or potentially execute arbitrary code with root privileges
on the X.Org server. (CVE-2007-6427)

An input validation flaw was found in the X.Org server's XFree86-Misc
extension. A malicious authorized client could exploit this issue to cause
a denial of service (crash), or potentially execute arbitrary code with
root privileges on the X.Org server. (CVE-2007-5760)

An information disclosure flaw was found in the X.Org server's TOG-CUP
extension. A malicious authorized client could exploit this issue to cause
a denial of service (crash), or potentially view arbitrary memory content
within the X server's address space. (CVE-2007-6428)

A flaw was found in the X.Org server's XC-SECURITY extension, that could
have allowed a local user to verify the existence of an arbitrary file,
even in directories that are not normally accessible to that user.
