Hello gophers, We have just released Go versions 1.16.4 and 1.15.12, minor point releases.
This minor release includes a security fix according to the new security policy (#44918 <https://golang.org/issue/44918>). ReadRequest and ReadResponse in net/http can hit an unrecoverable panic when reading a very large header (over 7MB on 64-bit architectures, or over 4MB on 32-bit ones). Transport and Client are vulnerable and the program can be made to crash by a malicious server. Server is not vulnerable by default, but can be if the default max header of 1MB is overridden by setting Server.MaxHeaderBytes to a higher value, in which case the program can be made to crash by a malicious client. This also affects golang.org/x/net/http2/h2c and HeaderValuesContainsToken in golang.org/x/net/http/httpguts, and is fixed in golang.org/x/net@v0.0.0-20210428140749-89ef3d95e781. This is issue #45710 <https://golang.org/issue/45710> and CVE-2021-31525. Thanks to Guido Vranken <https://twitter.com/GuidoVranken> who reported the crash as part of the Ethereum 2.0 bounty program <https://ethereum.org/en/eth2/get-involved/bug-bounty>.
