patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200405-09
(ProFTPD Access Control List bypass vulnerability)

ProFTPD 1.2.9 introduced a vulnerability that allows CIDR-based ACLs (such
as 10.0.0.1/24) to be bypassed. The CIDR ACLs are disregarded, with the net
effect being similar to an 'AllowAll' directive.

files to be downloaded and/or modified, thereby allowing a potential remote
compromise of the server.

Workaround :

Users may work around the problem by avoiding use of CIDR-based ACLs.
