This update for nginx to version 1.14.2 fixes the following issues :

Security vulnerabilities addressed :

CVE-2018-16843 CVE-2018-16844: Fixed an issue whereby a client using HTTP/2 might cause excessive memory consumption and CPU usage (bsc#1115025 bsc#1115022).

CVE-2018-16845: Fixed an issue which might result in worker process memory disclosure whne processing of a specially crafted mp4 file with the ngx_http_mp4_module (bsc#1115015).

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.

According to it's self reported version, the installed version of Nginx Plus is R1 (built on Open Source version 1.5.3-1) prior to R15-P2 or R16 (built on Open Source version 1.15.2) prior to R16-P1. It is,  therefore, affected by the following issues :

  - An unspecified error exists related to the module     'ngx_http_v2_module' that allows excessive memory usage.
    (CVE-2018-16843)

  - An unspecified error exists related to the module     'ngx_http_v2_module' that allows excessive CPU usage.
    (CVE-2018-16844)

  - An unspecified error exists related to the module     'ngx_http_mp4_module' that allows worker process     crashes or memory disclosure. (CVE-2018-16845)

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3812-1 advisory.

    It was discovered that nginx incorrectly handled the HTTP/2 implementation. A remote attacker could     possibly use this issue to cause excessive memory consumption, leading to a denial of service. This issue     only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 18.10. (CVE-2018-16843)

    Gal Goldshtein discovered that nginx incorrectly handled the HTTP/2 implementation. A remote attacker     could possibly use this issue to cause excessive CPU usage, leading to a denial of service. This issue     only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 18.10. (CVE-2018-16844)

    It was discovered that nginx incorrectly handled the ngx_http_mp4_module module. A remote attacker could     possibly use this issue with a specially crafted mp4 file to cause nginx to crash, stop responding, or     access arbitrary memory. (CVE-2018-16845)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:3680 advisory.

  - nginx: Excessive CPU usage via flaw in HTTP/2 implementation (CVE-2018-16844)

  - nginx: Denial of service and memory disclosure via mp4 module (CVE-2018-16845)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Three vulnerabilities were discovered in Nginx, a high-performance web and reverse proxy server, which could result in denial of service in processing HTTP/2 (via excessive memory/CPU usage) or server memory disclosure in the ngx_http_mp4_module module (used for server-side MP4 streaming).

An update of the nginx package has been released.
