net/http, net/textproto, mime/multipart: denial of service from excessive resource consumption
CVE: CVE-2023-24536
Component: golang
CWE: CWE-400
Severity: Moderate
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2023-04-04T00:00:00+00:00

A flaw was found in Golang Go, where it is vulnerable to a denial of service caused by an issue during multipart form parsing. By sending a specially crafted input, a remote attacker can consume large amounts of CPU and memory, resulting in a denial of service.

Statement: For Red Hat Enterprise Linux,

* Conmon uses Go in unit testing, but not functionally in the package. Go is used only in test files, hence, not in the actual code, thus, conmon is not-affected.
* The CVE refers to multipart form parsing routine mime/multipart.Reader.ReadForm, which is not used in Grafana, hence it is not-affected.
* Butane does not parse multipart forms, hence, it is also not-affected.
Redhat has marked this vulnerability as moderate as this vulnerability could lead to a potential denial of service when all the resource of a system is consumed which is technically not a clear case of denial of service.
