Package : fetchmail
Vulnerability : programming error
Problem type : local
Debian-specific: no
CVE ID : CVE-2005-3088
Debian Bug : 336096

Due to restrictive dependency definition the updated fetchmailconf
package couldn't be installed on the old stable distribution (woody)
together with fetchmail-ssl. Hence, this update loosens it, so that
the update can be pulled in. For completeness we're including the
original advisory text:

Thomas Wolff discovered that the fetchmailconfig program which is
provided as part of fetchmail, an SSL enabled POP3, APOP, IMAP mail
gatherer/forwarder, creates the new configuration in an insecure
fashion that can lead to leaking passwords for mail accounts to
local users.

This update also fixes a regression in the package for stable caused
by the last security update.

For the old stable distribution (woody) this problem has been fixed in
version 5.9.11-6.4.

For the stable distribution (sarge) this problem has been fixed in
version 6.2.5-12sarge3.

For the unstable distribution (sid) this problem has been fixed in
version 6.2.5.4-1.

We recommend that you upgrade your fetchmail package.
