Sebastian Krahmer of SUSE discovered the following two vulnerabilities:
|
||
|
|
</p>
|
||
|
|
<ul>
|
||
|
|
<li>udev does not verify the origin of NETLINK messages
|
||
|
|
properly (CVE-2009-1185).</li>
|
||
|
|
<li>A buffer overflow exists in the
|
||
|
|
util_path_encode() function in lib/libudev-util.c (CVE-2009-1186).</li>
|
||
|
|
</ul>
|
||
|
|

|
||
|
|
<impact type="high">
|
||
|
|
<p>
|
||
|
|
A local attacker could gain root privileges by sending specially
|
||
|
|
crafted NETLINK messages to udev or cause a Denial of Service.
|
||
|
|
</p>
|
||
|
|
</impact>
|
||
|
|
<workaround>
|
||
|
|
<p>
|
||
|
|
There is no known workaround at this time.
|
||
|
|
</p>
|
||
|
|
</workaround>
|
||
|
|
<resolution>
|
||
|
|
<p>
|
||
|
|
All udev users should upgrade to the latest version:
|
||
|
|
</p>
|
||
|
|
<code>
|
||
|
|
# emerge --sync
|
||
|
|
# emerge --ask --oneshot --verbose ">=sys-fs/udev-124-r2"</code>
