<p>vladz reported the following vulnerabilities in the X.Org X server:</p>
|
|
|
|
<ul>
|
|
<li>The X.Org X server follows symbolic links when trying to access the
|
|
lock file for a X display, showing a predictable behavior depending on
|
|
the file type of the link target (CVE-2011-4028).
|
|
</li>
|
|
<li>The X.Org X server lock file mechanism allows for a race condition to
|
|
cause the X server to modify the file permissions of an arbitrary file
|
|
to 0444 (CVE-2011-4029).
|
|
</li>
|
|
</ul>
|
|

|
<impact type="normal">
|
|
<p>A local attacker could exploit these vulnerabilities to disclose
|
|
information by making arbitrary files on a system world-readable or gain
|
|
information whether a specified file exists on the system and whether it
|
|
is a file, directory, or a named pipe.
