Other bug fixes and changes made: - Fixed an issue with handling of client addresses when using unix domain listen sockets to work with datagrams on Linux. - The logging level of the 'http request', 'https proxy request', 'unsupported protocol', 'version too low', 'no suitable key share', and 'no suitable signature algorithm' SSL errors has been lowered from 'crit' to 'info'. - Fixed an issue with using OpenSSL 1.1.0 or newer it was not possible to switch off 'ssl_prefer_server_ciphers' in a virtual server if it was switched on in the default server. - Fixed an issue with TLS 1.3 always being enabled when built with OpenSSL 1.1.0 and used with 1.1.1 - Fixed an issue with sending a disk-buffered request body to a gRPC backend - Fixed an issue with connections of some gRPC backends might not be cached when using the 'keepalive' directive. - Fixed a segmentation fault, which might occur in a worker process if the ngx_http_mp4_module was used on 32-bit platforms. - Fixed an issue, whereby working with gRPC backends might result in excessive memory consumption.

The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the .mp4. directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module.
