High Nessus Plugin ID 118754
SynopsisThe remote FreeBSD host is missing one or more security-related
DescriptionNGINX Team reports :
Two security issues were identified in nginx HTTP/2 implementation,
which might cause excessive memory consumption (CVE-2018-16843) and
CPU usage (CVE-2018-16844).
The issues affect 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.
A security issue was identified 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
isclosure by using a specially crafted mp4 file (CVE-2018-16845).
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.
SolutionUpdate the affected packages.
