发布于3月6日3月6日 Members FreeBSD: (Multiple Advisories) (CVE-2023-0464): OpenSSL -- Excessive Resource Usage Verifying X.509 Policy Constraints Severity 8 CVSS (AV:N/AC:L/Au:N/C:N/I:N/A:C) Published 03/22/2023 Created 03/27/2023 Added 03/24/2023 Modified 01/28/2025 Description A security vulnerability has been identified in all supported versions of OpenSSL related to the verification of X.509 certificate chains that include policy constraints.Attackers may be able to exploit this vulnerability by creating a malicious certificate chain that triggers exponential use of computational resources, leading to a denial-of-service (DoS) attack on affected systems. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function.
