(CVE-2019-15846) + + +Exim version 4.92.1 +------------------- + +JH/31 Avoid re-expansion in ${sort } expansion. (CVE-2019-13917, OVE-20190718-0006) + + +Since version 4.92 +------------------ + +JH/06 Fix buggy handling of autoreply bounce_return_size_limit, and a possible + buffer overrun for (non-chunking) other transports. + +JH/07 GnuTLS: Our use of late (post-handshake) certificate verification, under + TLS1.3, means that a server rejecting a client certificate is not visible + to the client until the first read of encrypted data (typically the + response to EHLO). Add detection for that case and treat it as a failed + TLS connection attempt, so that the normal retry-in-clear can work (if + suitably configured). + +JB/01 Bug 2375: fix expansions of 822 addresses having comments in local-part + and/or domain. Found and fixed by Jason Betts. + +JH/08 Add hardening against SRV & TLSA lookups the hit CNAMEs (a nonvalid + configuration). If a CNAME target was not a wellformed name pattern, a + crash could result. + +JH/09 Logging: Fix initial listening-on line for multiple ports for an IP when + the OS reports them interleaved with other addresses. + +JH/10 OpenSSL: Fix aggregation of messages. Previously, when PIPELINING was + used both for input and for a verify callout, both encrypted, SMTP + responses being sent by the server could be lost. This resulted in + dropped connections and sometimes bounces generated by a peer sending + to this system. + Exim version 4.92 ----------------- @@ -151,6 +192,49 @@ JH/32 For main options check_spool_space and check_inode_space, where the (i.e. more than 2 TB).

Previously + it was unset. + +JH/34 Increase RSA keysize of autogen selfsign cert from 1024 to 2048. RHEL 8.0 + OpenSSL didn't want to use such a weak key. Do for GnuTLS also, and for + more-modern GnuTLS move from GNUTLS_SEC_PARAM_LOW to + GNUTLS_SEC_PARAM_MEDIUM. + +JH/35 OpenSSL: fail the handshake when SNI processing hits a problem, server + side. Previously we would continue as if no SNI had been received. + +JH/36 Harden the handling of string-lists. When a list consisted of a sole + "<" character, which should be a list-separator specification, we walked + off past the nul-terimation. + +JH/37 Bug 2341: Send "message delayed" warning MDNs (restricted to external + causes) even when the retry time is not yet met. Previously they were + not, meaning that when (say) an account was over-quota and temp-rejecting, + and multiple senders' messages were queued, only one sender would get + notified on each configured delay_warning cycle. + +JH/38 Bug 2351: Log failures to extract envelope addresses from message headers. + +JH/39 OpenSSL: clear the error stack after an SSL_accept(). With anon-auth + cipher-suites, an error can be left on the stack even for a succeeding + accept; this results in impossible error messages when a later operation + actually does fail. + +AM/01 Bug 2359: GnuTLS: repeat lowlevel read and write operations while they + return error codes indicating retry. Under TLS1.3 this becomes required. + +JH/40 Fix the feature-cache refresh for EXPERIMENTAL_PIPE_CONNECT. Previously + it only wrote the new authenticators, resulting in a lack of tracking of + peer changes of ESMTP extensions until the next cache flush. + +JH/41 Fix the loop reading a message header line to check for integer overflow, + and more-often against header_maxsize. Previously a crafted message could + induce a crash of the recive process; now the message is cleanly rejected. + +JH/42 Bug 2366: Fix the behaviour of the dkim_verify_signers option.
