(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 ----------------- @@ -180,6 +216,20 @@ JH/39 OpenSSL: clear the error stack after an SSL_accept(). With anon-auth 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. It had + been totally disabled for all of 4.91. Discovery and fix by "Mad Alex". + Exim version 4.91 -----------------
