发布于3月6日3月6日 Members Red Hat: CVE-2023-27538: SSH connection too eager reuse still (Multiple Advisories) Severity 5 CVSS (AV:L/AC:L/Au:S/C:C/I:N/A:N) Published 03/30/2023 Created 11/09/2023 Added 11/08/2023 Modified 01/28/2025 Description An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously established SSH connection despite the fact that an SSH option was modified, which should have prevented reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if the configurations match. However, two SSH settings were omitted from the configuration check, allowing them to match easily, potentially leading to the reuse of an inappropriate connection.
