<description>
|
|
<p> "infamous42md" reported that ProFTPD is vulnerable to format
|
|
string vulnerabilities when displaying a shutdown message containing
|
|
the name of the current directory, and when displaying response
|
|
messages to the client using information retrieved from a database
|
|
using mod_sql.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could create a directory with a malicious name
|
|
that would trigger the format string issue if specific variables are
|
|
used in the shutdown message, potentially resulting in a Denial of
|
|
Service or the execution of arbitrary code with the rights of the user
|
|
running the ProFTPD server. An attacker with control over the database
|
|
contents could achieve the same result by introducing malicious
|
|
messages that would trigger the other format string issue when used in
|
|
server responses.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Do not use the "%C", "%R", or "%U" in shutdown messages, and do
|
|
not set the "SQLShowInfo" directive.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All ProFTPD users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-ftp/proftpd-1.2.10-r7"</code>
