<p>
glFTPd is a highly configurable FTP server with many features.

<description>
<p>
The glFTPd server is vulnerable to a buffer overflow in the 'dupescan'
program. This vulnerability is due to an unsafe strcpy() call which can
cause the program to crash when a large argument is passed.
</p>
</description>
<impact type="normal">
<p>
A local user with malicious intent can pass a parameter to the dupescan
program that exceeds the size of the buffer, causing it to overflow. This
can lead the program to crash, and potentially allow arbitrary code
execution with the permissions of the user running glFTPd, which could be
the root user.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All glFTPd users should upgrade to the latest version:
</p>
<code>
# emerge sync
# emerge -pv ">=net-ftp/glftpd-1.32-r1"
# emerge ">=net-ftp/glftpd-1.32-r1"</code>
</resolution>
