  script_tag(name:"insight", value:"This update for exim fixes the following issues:

exim was updated to 4.97.1 (boo#1218387, CVE-2023-51766):

 * Fixes for the smtp protocol smuggling (CVE-2023-51766)

exim was updated to exim 4.96:

 * Move from using the pcre library to pcre2.
 * Constification work in the filters module required a major version
 bump for the local-scan API. Specifically, the 'headers_charset'
 global which is visible via the API is now const and may therefore
 not be modified by local-scan code.
 * Bug 2819: speed up command-line messages being read in. Previously a
 time check was being done for every character, replace that with one
 per buffer.
 * Bug 2815: Fix ALPN sent by server under OpenSSL. Previously the string
 sent was prefixed with a length byte.
 * Change the SMTP feature name for pipelining connect to be compliant with
 RFC 5321. Previously Dovecot (at least) would log errors during
 submission.
 * Fix macro-definition during '-be' expansion testing. The move to
 write-protected store for macros had not accounted for these runtime
 additions, fix by removing this protection for '-be' mode.
 * Convert all uses of select() to poll().
 * Fix use of $sender_host_name in daemon process. When used in certain
 main-section options or in a connect ACL, the value from the first ever
 connection was never replaced for subsequent connections.
 * Bug 2838: Fix for i32lp64 hard-align platforms
 * Bug 2845: Fix handling of tls_require_ciphers for OpenSSL when a value
 with underbars is given.
 * Bug 1895: TLS: Deprecate RFC 5114 Diffie-Hellman parameters.
 * Debugging initiated by an ACL control now continues through into routing
 and transport processes.
 * The 'expand' debug selector now gives more detail, specifically on the
 result of expansion operators and items.
 * Bug 2751: Fix include_directory in redirect routers. Previously a
 bad comparison between the option value and the name of the file to
 be included was done, and a mismatch was wrongly identified.
 * Support for Berkeley DB versions 1 and 2 is withdrawn.
 * When built with NDBM for hints DB's check for nonexistence of a name
 supplied as the db file-pair basename.
 * Remove the 'allow_insecure_tainted_data' main config option and the
 'taint' log_selector.
 * Fix static address-list lookups to properly return the matched item.
 Previously only the domain part was returned.
 * The ${run} expansion item now expands its command string elements after
 splitting. Previously it was before, the new ordering makes handling
 zero-length arguments simpler.
 * Taint-check exec arguments for transport-initiated external processes.
 Previously, tainted values could be used. This affects 'pipe', 'lmtp' and
 'queryprogram' transport, transport-filter, and ETRN commands.
 The ${run} expansion is also affected: in 'preexpand' mode no part of
 the command line may be tainted, in default mode the executable name
 may not be tainted.
 * ... [Please see the references for more information on the vulnerabilities]");
