udev is the device manager used in the Linux 2.6 kernel series.
Sebastian Krahmer of SUSE discovered the following two vulnerabilities:
<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>
<impact type="high">
A local attacker could gain root privileges by sending specially
crafted NETLINK messages to udev or cause a Denial of Service.
There is no known workaround at this time.
All udev users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=sys-fs/udev-124-r2&quot;</code>
