Package: release.debian.org
Severity: normal
Tags: trixie
X-Debbugs-Cc: [email protected]
Control: affects -1 + src:dovecot
User: [email protected]
Usertags: pu
[ Reason ]
I'd like to update dovecot to pull in several bug fixes, both upstream and
in packaging. All of the bugs can potentially lead to availability issues,
either in the form of incorrectly delivered mail or an inability to retrieve
mail.
[ Impact ]
The following bugs are addressed by the attached debdiff:
#1116070 - segfault in lib-sieve in various scenarios
#1116328 - oauth token validation failure leading to authentication failures
that should have succeeded
#1112667 - typos and other minor fixes in the Debian-provided default
configuration
#1111469 - dovecot-lmtp: Debian-overridden auth_username_format wrongly
drops default case-insensitivity
[ Tests ]
Changes have been validated upstream and are all present in testing.
[ Risks ]
The changes are small and targeted, minimizing the risk.
[ Checklist ]
[*] *all* changes are documented in the d/changelog
[*] I reviewed all changes and I approve them
[*] attach debdiff against the package in (old)stable
[*] the issue is verified as fixed in unstable
[ Changes ]
