Pkgsrc changes: * Remove now integrated patch. Upstream changes: This release contains a number of security related fixes, contributed by X41 D-Sec. They have conducted a security audit of Unbound, funded by OSTIF. The previous CVEs fixed in 1.9.4 and 1.9.5 were the most important ones, less important fixes and side findings for more robust code have been included in this release, alongside a normal number of bug fixes. The sort order for included config snippets is now ascending by name, it previously was reversed due to an oversight. Most config snippets do not depend on the order as they add a stub or forward zone or some server: section config entries. Features: - The unbound.conf includes are sorted ascending, for include statements with a '*' from glob. - drop-tld.diff in contrib/ : adds option drop-tld: yesno that drops 2 label queries, to stop random floods. Apply with patch -p1 < contrib/drop-tld.diff and compile. From Saksham Manchanda (Secure64). Please note that we think this will drop DNSKEY and DS lookups for tlds and hence break DNSSEC lookups for downstream clients. - Add new configure option `--enable-fully-static` to enable full static build if requested; in relation to #91. - Add make distclean that removes everything configure produced, and make maintainer-clean that removes bison and flex output. - unbound-fuzzers.tar.bz2 in contrib/ : three programs for fuzzing, that are 1:1 replacements for unbound-fuzzme.c that gets created after applying the contrib/unbound-fuzzme.patch. They are contributed by Eric Sesterhenn from X41 D-Sec. Bug Fixes: - Fix that pkg-config is setup before --enable-systemd needs it. - Fix contrib/fastrpz.patch asprintf return value checks. - ipset module #28: log that an address is added, when verbosity high. - ipset: refactor long routine into three smaller ones. - updated Makefile dependencies. - squelch DNS over TLS errors 'ssl handshake failed crypto error' on low verbosity, they show on verbosity 3 (query details), because there is a high volume and the operator cannot do anything for the remote failure. Specifically filters the high volume errors. - Fix #71: fix openssl error squelch commit compilation error. - Fix #72: configure --with-syslog-facility=LOCAL0-7 with default LOG_DAEMON (as before) can set the syslog facility that the server uses to log messages. - Use explicit bzero for wiping clear buffer of hash in cachedb, reported by Eric Sesterhenn from X41 D-Sec. - Fix #78: Memory leak in outside_network.c. - Merge pull request #76 from Maryse47: Improvements and fixes for systemd unbound.service. - oss-fuzz badge on README.md. - Fix fix for #78 to also free service callback struct. - Fix for oss-fuzz build warning. - Fix wrong response ttl for prepended short CNAME ttls, this would create a wrong zero_ttl response count with serve-expired enabled. - Merge #80 from stasic: Improve wording in man page. - Merge #82 from hardfalcon: Downgrade CAP_NET_ADMIN to CAP_NET_RAW in unbound.service. - Merge #81 from Maryse47: Consistently use /dev/urandom instead of /dev/random in scripts and docs. - Merge #83 from Maryse47: contrib/unbound.service.in: do not fork into the background. - Merge #85 for #84 from sam-lunt: Add kill capability to systemd service file to fix that systemctl reload fails. - Merge #87 from hardfalcon: Fix contrib/unbound.service.in, Drop CAP_KILL, use + prefix for ExecReload= instead. - Merge #90 from vcunat: fix build with nettle-3.5. - Fix for CVE-2019-16866. That fix is also in 1.9.4. - Merge #86 from psquarejho: Added -b source address option to smallapp/unbound-anchor.c, from Lukas Wunner. - Add doxygen comments to unbound-anchor source address code, in #86. - Merge #97: manpage: Add missing word on unbound.conf, from Erethon. - Fix #99: Memory leak in ub_ctx (event_base will never be freed). - Fix #109: check number of arguments for stdin-pipes in unbound-control and fail if too many arguments. - Merge #102 from jrtc27: Add getentropy emulation for FreeBSD. - iana portlist updated. - contrib/fastrpz.patch updated to apply for current code. - fixes for splint cleanliness, long vs int in SSL set_mode. - In unbound-host use separate variable for get_option to please code checkers. - update to bison output of 3.4.1 in code repository. - Provide a prototype for compat malloc to remove compile warning. - Portable grep usage for reuseport configure test. - Check return type of HMAC_Init_ex for openssl 0.9.8. - gitignore .source tempfile used for compatible make. - Fix for CVE-2019-18934, shell execution in ipsecmod.
