Security update for nginx
This update for nginx fixes the following issues:
nginx was updated to 1.14.2:
- Bugfix: nginx could not be built on Fedora 28 Linux.
- Bugfix: in handling of client addresses when using unix domain listen sockets to work with datagrams on Linux.
- Change: 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'.
- Bugfix: when 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.
- Bugfix: nginx could not be built with LibreSSL 2.8.0.
- Bugfix: if nginx was built with OpenSSL 1.1.0 and used with OpenSSL 1.1.1, the TLS 1.3 protocol was always enabled.
- Bugfix: sending a disk-buffered request body to a gRPC backend might fail.
- Bugfix: connections with some gRPC backends might not be cached when using the 'keepalive' directive.
- Bugfix: a segmentation fault might occur in a worker process if the ngx_http_mp4_module was used on 32-bit platforms.
Changes with nginx 1.14.1:
- Security: when using HTTP/2 a client might cause excessive memory consumption (CVE-2018-16843) and CPU usage (CVE-2018-16844).
- Security: processing of a specially crafted mp4 file with the ngx_http_mp4_module might result in worker process memory disclosure (CVE-2018-16845).
- Bugfix: working with gRPC backends might result in excessive memory consumption.
Changes with nginx 1.13.12:
- Bugfix: connections with gRPC backends might be closed unexpectedly when returning a large response.
Changes with nginx 1.13.10
- Feature: the 'set' parameter of the 'include' SSI directive now allows writing arbitrary responses to a variable; the 'subrequest_output_buffer_size' directive defines maximum response size.
- Feature: now nginx uses clock_gettime(CLOCK_MONOTONIC) if available, to avoid timeouts being incorrectly triggered on system time changes.
- Feature: the 'escape=none' parameter of the 'log_format' directive. Thanks to Johannes Baiter and Calin Don.
- Feature: the $ssl_preread_alpn_protocols variable in the ngx_stream_ssl_preread_module.
- Feature: the ngx_http_grpc_module.
- Bugfix: in memory allocation error handling in the 'geo' directive.
- Bugfix: when using variables in the 'auth_basic_user_file' directive a null character might appear in logs. Thanks to Vadim Filimonov.

Описание
nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive memory consumption. This issue affects nginx compiled with the ngx_http_v2_module (not compiled by default) if the 'http2' option of the 'listen' directive is used in a configuration file.

Описание
nginx before versions 1.15.6, 1.14.1 has a vulnerability in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted mp4 file. 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.
