From: Bernd Kuhls Date: Sun, 28 Jul 2019 08:50:47 +0000 (+0200) Subject: package/exim: security bump to version 4.92.1 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1d3fe88d084410b0ba55e9ae0ceef19351bbcf99;p=buildroot.git package/exim: security bump to version 4.92.1 Fixes CVE-2019-13917: http://www.exim.org/static/doc/security/CVE-2019-13917.txt https://github.com/Exim/exim/commit/d185889f47b9b27088e777f7d382295c51271586 added new code to "Prebuild the data structure for builtin macros". This function needs a host-built binary called macro_predef, it depends on host-berkeleydb, host-pcre and optionally on host-openssl. With an openssl-enabled exim the host build of macro_predef will fail if host-openssl is missing: /usr/bin/gcc -DMACRO_PREDEF macro_predef.c In file included from hash.h:14, from exim.h:485, from macro_predef.c:11: sha_ver.h:37:12: fatal error: openssl/ssl.h: No such file or directory because macro_predef also has the an optional dependency on openssl: https://github.com/Exim/exim/blob/exim-4.92%2Bfixes/src/src/macro_predef.c#L130 Removed patches applied upstream: 0004: https://github.com/Exim/exim/commit/98913c8ea2be5188dd22ec652da1182017e8edb7 0005: https://github.com/Exim/exim/commit/cf3cd306062a08969c41a1cdd32c6855f1abecf1 0007: https://github.com/Exim/exim/commit/7ea1237c783e380d7bdb86c90b13d8203c7ecf26#diff-58af16fe62ea674adf1730edc078d175R6243 Added patch to fix uClibc build.
