[Backports-security-announce] Security Update for proftpd-dfsg

Francesco P. Lovergine uploaded new packages for proftpd-dfsg which fixed the
following security problem:

CVE-2009-3639

The mod_tls module in ProFTPD before 1.3.2b, and 1.3.3 before 1.3.3rc2,
when the dNSNameRequired TLS option is enabled, does not properly
handle a '\0' character in a domain name in the Subject Alternative
Name field of an X.509 client certificate, which allows remote
attackers to bypass intended client-hostname restrictions via a crafted
certificate issued by a legitimate Certification Authority, a related
issue to CVE-2009-2408.

For the etch-backports distribution the problems have been fixed in
version 1.3.1-17lenny4~bpo40+1.

For the lenny and sid distributions the problems have been fixed in version
1.3.1-17lenny4 and 1.3.2b-1.

Upgrade instructions

If you don't use pinning (see [1]) you have to update the packages
