DLA-1572-1 nginx -- LTS security update

Date Reported:

08 Nov 2018

Affected Packages:

nginx

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2018-16845.

More information:

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.
