Debian DLA-1572-1 : nginx security update

High Nessus Plugin ID 118839

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
