tag_insight = "Due to a version numbering problem, the Postfix update for DSA 1629 was
not installable on the i386 (Intel ia32) architecture. This update
increases the version number to make it installable on i386 as well.
For reference the original advisory text is below.

Sebastian Krahmer discovered that Postfix, a mail transfer agent,
incorrectly checks the ownership of a mailbox. In some configurations,
this allows for appending data to arbitrary files as root.

Note that only specific configurations are vulnerable; the default
Debian installation is not affected. Only a configuration meeting
the following requirements is vulnerable:
* The mail delivery style is mailbox, with the Postfix built-in
local(8) or virtual(8) delivery agents.
* The mail spool directory (/var/spool/mail) is user-writeable.
* The user can create hardlinks pointing to root-owned symlinks
located in other directories.

For a detailed treating of the issue, please refer to the upstream
author's announcement:
http://article.gmane.org/gmane.mail.postfix.announce/110

For the stable distribution (etch), this problem has been fixed in
version 2.3.8-2+etch1.

For the testing distribution (lenny), this problem has been fixed in
version 2.5.2-2lenny1.

For the unstable distribution (sid), this problem has been fixed
in version 2.5.4-1.

We recommend that you upgrade your postfix package.";
