Debian Security Advisory
DLA-2485-1 golang-golang-x-net-dev -- LTS security update
- 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.
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.
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.
