DESCRIPTION:
A security issue has been reported in ProFTPD, which can be exploited
by malicious people to compromise a vulnerable system.

The security issue is caused due to the distribution of compromised
ProFTPD 1.3.3c source code packages via the project's main FTP server
and all of the mirror servers, which contain a backdoor allowing
remote root access.

The compromised files were distributed from November 28th 2010 to
December 2nd 2010.

SOLUTION:
Check and validate your copy of the source code.
