Vulnerability Details

CVEID:CVE-2019-7401
**DESCRIPTION:**NGINX Unit before 1.7.1 might allow an attacker to cause a heap-based buffer overflow in the router process with a specially crafted request. This may result in a denial of service (router process crash) or possibly have unspecified other impact.

CVEID:CVE-2018-16843
**DESCRIPTION:**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.

CVEID:CVE-2018-16845
**DESCRIPTION:**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.
