OESA-2025-1168 — etcd security update

Affected: openEuler:20.03-LTS-SP4: etcd

%{expand: Security Fix(es):

Authentication vulnerability found in Etcd-io v.3.4.10 allows remote attackers to escalate privileges via the debug function.(CVE-2021-28235)

Parsing malicious or large YAML documents can consume excessive amounts of CPU or memory.(CVE-2022-3064)

Etcd v3.5.4 allows remote attackers to cause a denial of service via function PageWriter.write in pagewriter.go. NOTE: the vendor's position is that this is not a vulnerability.(CVE-2022-34038)

A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of small requests.(CVE-2022-41723)

etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.4.26 and 3.5.9, the LeaseTimeToLive API allows access to key names (not value) associated to a lease when `Keys` parameter is true, even a user doesn't have read permission to the keys. The impact is limited to a cluster which enables auth (RBAC). Versions 3.4.26 and 3.5.9 fix this issue. There are no known workarounds.(CVE-2023-32082)
