Date Reported:
09 Dec 2020
Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2019-9512, CVE-2019-9514.
More information:

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.
