| Description: | Summary:
The remote host is missing an update for the Debian 'golang-golang-x-net-dev' package(s) announced via the DLA-2485-1 advisory.
Vulnerability Insight:
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.
