  • 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.


  • 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
