c-ares version 1.16.1
Security:
o 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:
o 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:
o Fix Windows Unicode incompatibilities with ares_getaddrinfo() [1]
o Silence false cast-align compiler warnings due to valid casts of
struct sockaddr to struct sockaddr_in and struct sockaddr_in6.
o MacOS should use libresolv for retrieving DNS servers, like iOS
o CMake build system should populate the INCLUDE_DIRECTORIES property of
installed targets [2]
o Correct macros in use for the ares_getaddrinfo.3 man page
