high Nessus Plugin ID 143594
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security update.

Description

The http2 server support in this package was vulnerable to certain types of DOS attacks.

CVE-2019-9512

This code was vulnerable to ping floods, potentially leading to a denial of service. The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses.
Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.

CVE-2019-9514

This code was vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.

For Debian 9 stretch, these problems have been fixed in version 1:0.0+git20161013.8b4af36+dfsg-3+deb9u1.

We recommend that you upgrade your golang-golang-x-net-dev packages.

For the detailed security status of golang-golang-x-net-dev please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/golang-golang-x-net-dev

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.
