+Exim version 4.95
+-----------------
+
+JH/01 Bug 1329: Fix format of Maildir-format filenames to match other mail-
+ related applications. Previously an "H" was used where available info
+ says that "M" should be, so change to match.
+
+JH/02 Bug 2587: Fix pam expansion condition. Tainted values are commonly used
+ as arguments, so an implementation trying to copy these into a local
+ buffer was taking a taint-enforcement trap. Fix by using dynamically
+ created buffers.
+
+JH/03 Bug 2586: Fix listcount expansion operator. Using tainted arguments is
+ reasonable, eg. to count headers. Fix by using dynamically created
+ buffers rather than a local. Do similar fixes for ACL actions "dcc",
+ "log_reject_target", "malware" and "spam"; the arguments are expanded
+ so could be handling tainted values.
+
+JH/04 Bug 2590: Fix -bi (newaliases). A previous code rearrangement had
+ broken the (no-op) support for this sendmail command. Restore it
+ to doing nothing, silently, and returning good status.
+
+
Exim version 4.94
-----------------
- the autoreply transport file, log and once options
- file names used by the redirect router (including filter files)
- named-queue names
+ - paths used by single-key lookups
Previously this was permitted.
JH/21 Bug 2501: Fix init call in the heimdal authenticator. Previously it
JH/29 Bug 2537: Fix $mime_part_count. When a single connection had a non-mime
message following a mime one, the variable was not reset.
+JH/30 When an pipelined-connect fails at the first response, assume incorrect
+ cached capability (perhaps the peer reneged?) and immediately retry in
+ non-pipelined mode.
+
+JH/31 Fix spurious detection of timeout while writing to transport filter.
+
+JH/32 Bug 2541: Fix segfault on bad cmdline -f (sender) argument. Previously
+ an attempt to copy the string was made before checking it.
+
+JH/33 Fix the dsearch lookup to return an untainted result. Previously the
+ taint of the lookup key was maintained; we now regard the presence in the
+ filesystem as sufficient validation.
+
+JH/34 Fix the readsocket expansion to not segfault when an empty "options"
+ argument is supplied.
+
+JH/35 The dsearch lookup now requires that the directory is an absolute path.
+ Previously this was not checked, and nonempty relative paths made an
+ access under Exim's current working directory.
+
+JH/36 Bug 2554: Fix msg:defer event for the hosts_max_try_hardlimit case.
+ Previously no event was raised.
+
+JH/37 Bug 2552: Fix the check on spool space during reception to use the SIZE
+ parameter supplied by the sender MAIL FROM command. Previously it was
+ ignored, and only the check_spool_space option value for the required
+ leeway checked.
+
+JH/38 Fix $dkim_key_length. This should, after a DKIM verification, present
+ the size of the signing public-key. Previously it was instead giving
+ the size of the signature hash.
+
+JH/39 DKIM verification: the RFC 8301 restriction on sizes of RSA keys is now
+ the default. See the (new) dkim_verify_min_keysizes option.
+
+JH/40 Fix a memory-handling bug: when a connection carried multiple messages
+ and an ACL use a lookup for checking either the local_part or domain,
+ stale data could be accessed. Ensure that variable references are
+ dropped between messages.
+
+JH/41 Bug 2571: Fix SPA authenticator. Running as a server, an offset supplied
+ by the client was not checked as pointing within response data before
+ being used. A malicious client could thus cause an out-of-bounds read and
+ possibly gain authentication. Fix by adding the check.
+
+JH/42 Internationalisation: change the default for downconversion in the smtp
+ transport to be "if needed". Previously it was "as previously set" for
+ the message, which usually meant "if needed" for message-submission but
+ "no" for everything else. However, MTAs have been seen using SMTPUTF8
+ even when the envelope addresses did not need it, resulting in forwarding
+ failures to non-supporting MTAs. A downconvert in such cases will be
+ a no-op on the addresses, merely dropping the use of SMTPUTF8 by the
+ transport. The change does mean that addresses needing conversion will
+ be converted when previously a delivery failure would occur.
+
+JH/43 Fix possible long line in DSN. Previously when a very long SMTP error
+ response was received it would be used unchecked in a fail-DSN, violating
+ standards on line-length limits. Truncate if needed.
+
+HS/01 Remove parameters of the link to www.open-spf.org. The linked form
+ doesn't work. (Additionally add a new main config option to configure the
+ spf_smtp_comment)
