affect Exim's operation, with an unchanged configuration file. For new
options, and new features, see the NewStuff file next to this ChangeLog.
-Exim version 4.98
------------------
-
-JH/01 Support list of dkim results in the dkim_status ACL condition, making
- it more usable in the data ACL.
-
-JH/02 Bug 3040: Handle error on close of the spool data file during reception.
- Previously This was only logged, on the assumption that errors would be
- seen for a previous fflush(). However, a fuse filesystem has been
- reported as showing this an error for the fclose(). The spool is now in
- an uncertain state, and we have logged and responded acceptance. Change
- this to respond with a temp-reject, wipe spoolfiles, and log the error
- detail.
-
-JH/03 Bug 3030: Fix handling of DNS servfail respons for DANE TLSA. When hit
- during a recipient verify callout, a QUIT command was attempted on the
- now-closed callout channel, causing a paniclog entry.
-
-JH/04 Bug 3039: Fix handling of of an empty log_reject_target, with
- a connection_reject log_selector, under tls_on_connect. Previously
- with this combination, when the connect ACL rejected, a spurious
- paniclog entry was made.
-
-JH/05 Fix TLS resumption for TLS-on-connect. This was broken by the advent
- of loadbalancer-detection for resumption, in 4.96 - which tries to
- use the EHLO response. SMTPS does not have one at the time it is starting
- TLS. Change the default for the smtp transport host_name_extract option
- to be a static string, for TLS-on-connect cases; meaning that resumption
- will always be attempted (unless deliberately overriden).
-
-JH/06 Bug 3054: Fix dnsdb lookup for a TXT record with multiple chunks, with a
- chunk-separator specification. This was broken by hardening introduced
- for Bug 3031.
-
-JH/07 Bug 3050: Fix -bp for old message_id format spoolfiles. Previously it
- included the -H with the id; this also messed up exiqgrep.
-
-JH/08 Bug 3056: Tighten up parsing of DKIM DNS records. Previously, whitespace
- was not properly skipped and empty elements would cause mis-parsing.
- Tighten parsing of DKIM header records. Previously, all but lowercase
- alpha chars would be ignored in potential tag names.
-
-JH/09 Bug 3057: Add heuristic for spotting mistyped IPv6 addresses in lists
- being searched. Previously we only had one for IPv4 addresses. Per the
- documentation, the error results by default in a no-match result for the
- list. It is logged if the unknown_in_list log_selector is used.
-
-JH/10 Bug 3058: Ensure that a failing expansion in a router "set" option defers
- the routing operation. Previously it would silently stop routing the
- message.
+Since Exim version 4.97
+-----------------------
-JH/11 Bug 3046: Fix queue-runs. Previously, the arrivel of a notification or
- info-request event close in time to a scheduled run timer could result in
- the latter being missed, and no further queue scheduled runs being
- initiated. This ouwld be more likely on high-load systems.
-
-JH/12 Refuse to accept a line "dot, LF" as end-of-DATA unless operating in
+JH/s1 Refuse to accept a line "dot, LF" as end-of-DATA unless operating in
LF-only mode (as detected from the first header line). Previously we did
accept that in (normal) CRLF mode; this has been raised as a possible
- attack scenario (under the name "smtp smuggling").
-
+ attack scenario (under the name "smtp smuggling", CVE-2023-51766).
