Fedora 37 : strongswan (2023-25800591ef)

critical Nessus Plugin ID 172470

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 37 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2023-25800591ef advisory.

- strongSwan 5.9.8 and 5.9.9 potentially allows remote code execution because it uses a variable named public for two different purposes within the same function. There is initially incorrect access control, later followed by an expired pointer dereference. One attack vector is sending an untrusted client certificate during EAP-TLS. A server is affected only if it loads plugins that implement TLS-based EAP methods (EAP-TLS, EAP-TTLS, EAP-PEAP, or EAP-TNC). This is fixed in 5.9.10. (CVE-2023-26463)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected strongswan package.
