Wed Jul 8 20:35:17 UTC 2020 - Matthias Eliasson <elimat@opensuse.org>
- Version update to 1.16.1
Security:
* Prevent possible use-after-free and double-free in ares_getaddrinfo() if
ares_destroy() is called prior to ares_getaddrinfo() completing.
Reported by Jann Horn at Google Project Zero.
Changes:
* Allow TXT records on CHAOS qclass. Used for retriving things like
version.bind, version.server, authoris.bind, hostname.bind, and id.server. [3]
Bug fixes:
* Fix Windows Unicode incompatibilities with ares_getaddrinfo() [1]
* Silence false cast-align compiler warnings due to valid casts of struct
sockaddr to struct sockaddr_in and struct sockaddr_in6.
* MacOS should use libresolv for retrieving DNS servers, like iOS
* CMake build system should populate the INCLUDE_DIRECTORIES property of
installed targets [2]
* Correct macros in use for the ares_getaddrinfo.3 man page
- Changes in version 1.16.0
Changes:
* Introduction of ares_getaddrinfo() API which provides similar output
(including proper sorting as per RFC 6724) to the system native API, but
utilizes different data structures in order to provide additional
information such as TTLs and all aliases. Please reference the respective
man pages for usage details.
* Parse SOA records from ns_t_any response
* CMake: Provide c-ares version in package export file
* CMake: Add CPACK functionality for DEB and RPM
* CMake: Generate PDB files during build
* CMake: Support manpage installation
Bug fixes:
* Fix bad expectation in IPv6 localhost test.
* AutoTools: use XC_CHECK_BUILD_FLAGS instead of XC_CHECK_USER_FLAGS to
prevent complaints about CPPFLAGS in CFLAGS.
* Fix .onion handling
* Command line usage was out of date for adig and ahost.
* Typos in manpages
* If ares_getenv is defined, it must return a value on all platforms
* If /etc/resolv.conf has invalid lookup values, use the defaults.
* Tests: Separate live tests from SetServers* tests as only live tests
should require internet access.
* ares_gethostbyname() should return ENODATA if no valid A or AAAA record
is found, but a CNAME was found.
* CMake: Rework library function checking to prevent unintended linking
with system libraries that aren't needed.
* Due to use of inet_addr() it was not possible to return 255.255.255.255
from ares_gethostbyname().
* CMake: Fix building of tests on Windows
- Drop regression.patch which have been fixed upstream
- Refresh disable-live-tests.patch
- Remove static lib since its required when doing tests and we dont want it
included in package
- Run spec-cleaner

commit 9413d54ff43d18cedf0d4531408aabc7c2c102a2
Author: Adam Majer <amajer@suse.de>
Date: Mon Feb 3 15:19:08 2020 +0100
Only count valid addresses when response parsing
When ares_parse_a_reply or ares_parse_aaaa_reply is called in case
where another AAAA and A responses exist, the resulting ares_addrttl
count is invalid and the structure points to gibberish.
This is a regression since 1.15.
