+++ This bug was initially created as a clone of Bug #210312 +++

Two issues in XFree86/xorg Xsession were reported and fixed upstream.  Both
relate to the handling of the xsession file.  

CVE-2006-5214: A local attacker could open for reading a users
~/.xsession-errors file if they are able to win a race during it's creation and
have sufficient privileges (+x) to the victims home directory already.

CVE-2006-5215: A local attacker could perform a temporary file attack on the
xsession error file created in /tmp and cause it to overwrite particular files
of the victim.  However this file is only created if the ability to create
~/.xsession-errors in the victims home directory fails, (something the attacker
has no control over).  The upstream Xsession code was different (and worse) than
our xinitrc code, but we should use mkstemp.

We've rated these issues as low severity and they can be deferred until a future
update for some other reason.

Affects: FC6, FC5
Note also affects xinitrc (bz#210311)
