Francesco P. Lovergine uploaded new packages for proftpd-dfsg which fixed the following security problem:
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.
If you don't use pinning (see ) you have to update the packages manually via "apt-get -t etch-backports install <packagelist>" with the packagelist of your installed packages affected by this update.  <http://backports.org/dokuwiki/doku.php?id=instructions>
We recommend to pin the backports repository to 200 so that new versions of installed backports will be installed automatically:
Package: * Pin: release a=etch-backports Pin-Priority: 200
