|
Przemyslaw Frasunek discovered several flaws in lukemftpd, which also apply
|
|
to Heimdal ftpd's out-of-band signal handling code.
|
|
</p>
|
|
<p>
|
|
Additionally, a potential vulnerability that could lead to Denial of
|
|
Service by the Key Distribution Center (KDC) has been fixed in this
|
|
version.

<impact type="high">
|
|
<p>
|
|
A remote attacker could be able to run arbitrary code with escalated
|
|
privileges, which can result in a total compromise of the server.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

<resolution>
|
|
<p>
|
|
All Heimdal users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
|
|
# emerge -pv ">=app-crypt/heimdal-0.6.3"
|
|
# emerge ">=app-crypt/heimdal-0.6.3"</code>
