CVE: CVE-2022-23772
Component: golang
CWE: CWE-190
Severity: Moderate
CVSS v3: 7.5/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Release date: 2022-01-19T00:00:00+00:00

A flaw was found in the big package of the math library in golang. The Rat.SetString could cause an overflow, and if left unhandled, it could lead to excessive memory use. This issue could allow a remote attacker to impact the availability of the system.
