For new options, and new features, see the NewStuff file next to this ChangeLog. +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. Similar fix for radius expansion condition. + +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. + +JH/05 Bug 2593: Fix "vacation" in Exim filter. Previously, when a "once" + record path was given (or the default used) without a leading directory + path, an error occurred on trying to open it. Use the transport's working + directory. + +JH/06 Bug 2594: Change the name used for certificate name checks in the smtp + transport. Previously it was the name on the DNS A-record; use instead + the head of the CNAME chain leading there (if there is one). This seems + to align better with RFC 6125. + +JH/07 Bug 2597: Fix a resource leak. Using a lookup in obtaining a value for + smtp_accept_max_per_host allocated resources which were not released + when the limit was exceeded. This eventually crashed the daemon. Fix + by adding a relase action in that path. + +JH/08 Bug 2598: Fix verify ACL condition. The options for the condition are + expanded; previously using tainted values was rejected. Fix by using + dynamically-created buffers. + +JH/09 Relax restrictions on ACL verify condition needing access to message + headers. Previously they were only permitted in data and non-smtp ACLs; + permit also mime, dkim, prdr quit and notquit. Applies to header-syntax, + not_blind, header_sender and header_names_ascii verification. + +JH/10 Bug 2603: Fix coding of string copying to only evaluate arguments once. + Previously a macro used one argument twice; when called with the + argument as an expression having side-effects, incorrect operation + resulted. Use an inlineable function. + +JH/11 Bug 2604: Fix request to cutthrough-deliver when a connection is already + held open for a verify callout. Previously this wan not accounted for + and a corrupt onward SMTP conversation resulted. + +JH/12 Bug 2607: Fix the ${srs_encode } expansion to handle quoted local_parts. + Previously they were embedded naively in the constructed address; when + needed, strip the quoting and quote the entire local_part. + Also make the inbound_srs expansion condition handle quoting. + + + Exim version 4.94 ----------------- @@ -184,6 +246,29 @@ JH/40 Fix a memory-handling bug: when a connection carried multiple messages 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.
