Summary
Red Hat Security Advisory: Red Hat OpenStack Platform (etcd) security update
Notes
Topic
An update for etcd is now available for Red Hat OpenStack Platform.
Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.
Details
etcd is a highly-available key value store for shared configuration.
The following Important impact security fix(es) are applicable to Red Hat OpenStack Platform 17.0 (Wallaby), 16.2 (Train), and 16.1 (Train):
* Improve heuristics preventing CPU/memory abuse by parsing malicious or
large YAML documents (CVE-2022-3064)
As a result of being built by golang 1.18.9, the following Moderate impact security fix(es) are applicable to Red Hat OpenStack Platform 16.2 and 16.1:
* golang: net/http: improper sanitization of Transfer-Encoding header (CVE-2022-1705)
* golang: net/http/httputil: ReverseProxy should not forward unparseable query parameters (CVE-2022-2880)
* golang: net/http: handle server errors after sending GOAWAY (CVE-2022-27664)
* golang: io/fs: stack exhaustion in Glob (CVE-2022-30630)
* golang: path/filepath: stack exhaustion in Glob (CVE-2022-30632)
* golang: encoding/gob: stack exhaustion in Decoder.Decode (CVE-2022-30635)
* golang: net/http/httputil: NewSingleHostReverseProxy - omit X-Forwarded-For not working (CVE-2022-32148)
* golang: regexp/syntax: limit memory used by parsing regexps (CVE-2022-41715)
* golang: net/http: An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests (CVE-2022-41717)
As a result of being built by golang 1.18.9, the following Low impact security fix(es) are applicable to Red Hat OpenStack Platform 16.2 and 16.1:
* golang: crypto/tls: session tickets lack random ticket_age_add (CVE-2022-30629)
* golang: math/big: decoding big.Float and big.Rat types can panic if the encoded message is too short, potentially allowing a denial of service (CVE-2022-32189)

score, acknowledgments, and other related information, refer to the CVE

This issue could permit query parameter smuggling when a Go proxy forwards a parameter with an unparseable value. After the fix, the reverse proxy sanitizes the query parameters in the forwarded query when the outbound request\u0027s form field is set after the reverse proxy. The director function returns, indicating that the proxy has parsed the query parameters. Proxies that do not parse query parameters continue to forward the original query parameters unchanged.",
