Package: release.debian.org
Severity: normal
Tags: bookworm
User: release.debian@packages.debian.org
Usertags: pu
[ Reason ]
First in the normal series of postfix bug fix updates for bookworm.
[ Impact ]
User will continue to experience the bugs that are fixed by the update.
[ Tests ]
The package has a resonably comprehensive autopkgtest. Am currently
testing the update locally without issue.
[ Risks ]
Risks are low. So far the experience with these Postfix updates has
been very good. Upstream is well regarded for code quality and keeping
maintenance updates focused on changes that are generally in line with
Debian's post-release update policy.
[ Checklist ]
[X] *all* changes are documented in the d/changelog
[X] I reviewed all changes and I approve them
[X] attach debdiff against the package in (old)stable
[X] the issue is verified as fixed in unstable

* Refresh patches
[Wietse Venema]
* 3.7.6
- Bugfix (defect introduced: Postfix 1.0): the command "postconf
.. name=v1 .. name=v2 .." (multiple instances of the same
parameter name) created multiple name=value entries with
the same parameter name. It now logs a warning and skips
the earlier update. Found during code maintenance. File:
postconf/postconf_edit.c
- Bugfix (defect introduced: Postfix 3.3): the command "postconf
-M name1/type1='name2 type2 ...'" died with a segmentation
violation when the request matched multiple master.cf
entries. The master.cf file was not damaged. Problem reported
by SATOH Fumiyasu. File: postconf/postconf_master.c.
- Bugfix (defect introduced: Postfix 2.11): the command
"postconf -M name1/type1='name2 type2 ...'" could add a
service definition to master.cf that conflicted with an
already existing service definition. It now replaces all
existing service definitions that match the service pattern
'name1/type1' or the service name and type in 'name2 type2
...' with a single service definition 'name2 type2 ...'.
Problem reported by SATOH Fumiyasu. File: postconf/postconf_edit.c.
- Bitrot: preliminary support for OpenSSL configuration files,
primarily OpenSSL 1.1.1b and later. This introduces new
parameters "tls_config_file" and "tls_config_name", which
can be used to limit collateral damage from OS distributions
that crank up security to 11, increasing the number of
plaintext email deliveries. Details are in the postconf(5)
manpage under "tls_config_file" and "tls_config_name".

tls/tls_proxy_client_scan.c, tls/tls_proxy.h, tls/tls_server.c,
tlsproxy/tlsproxy.c.
- Cleanup: use TLS_CLIENT_PARAMS to pass the OpensSSL 'init'
configurations. This information is independent from the
client or server TLS context, and therefore does not belong
in tls_*_init() or tls_*_start() calls. The tlsproxy(8)
server uses TLS_CLIENT_PARAMS to report differences between
its own global TLS settings, and those from its clients.

tls/tls_proxy.h, tlsproxy/tlsproxy.c.
- Cleanup: reverted cosmetic-only changes to minimize the
patch footprint for OpenSSL INI file support; updated daemon
manpages with the new tls_config_file and tls_config_name
configuration parameters. Files: smtp/smtp.c, smtpd/smtpd.c,
tls/tls_client.c, tls/tls.h, tls/tls_server.c, tlsproxy/tlsproxy.c,
- Cleanup: made OpenSSL 'default' INI file support error
handling consistent with OpenSSL default behavior. Viktor
Dukhovni. Files: proto/postconf.proto, tls/tls_misc.c.
- Backwards compatibility for stable releases that originally
had no OpenSSL INI support. Skip the new OpenSSL INI support
code, unless the Postfix configuration actually specifies
non-default tls_config_xxx settings. File: tls/tls_misc.c.
- Cleanup: added a multiple initialization guard in the
tls_library_init() function, and made an initialization
error sticky. File: tls/tls_misc.c.
- Security: new parameter smtpd_forbid_unauth_pipelining
(default: no) to disconnect remote SMTP clients that violate
RFC 2920 (or 5321) command pipelining constraints. Files:
global/mail_params.h, smtpd/smtpd.c, proto/postconf.proto.
[ Other info ]
These fixes will be aligned to postfix 3.8.1 in testing/unstable, which
has been uploaded.
