Package        : nginx
Version        : 1.6.2-5+deb8u6
CVE ID         : CVE-2018-16845
Debian Bug     : #913090

It was discovered that there was a denial of service (DoS) vulnerability
in the nginx web/proxy server.

As there was no validation for the size of a 64-bit atom in an MP4 file,
this could have led to a CPU hog when the size was 0, or various other
problems due to integer underflow when the calculating atom data size,
including segmentation faults or even worker-process memory disclosure.

For Debian 8 "Jessie", this issue has been fixed in nginx version
1.6.2-5+deb8u6.

We recommend that you upgrade your nginx packages.


Regards,
