Package : strongswan CVE ID : CVE-2026-47895 Debian Bug : Elliott Childre identified a vulnerability in strongSwan, an IKE/IPsec suite. The bug happens when cloning certain identities and can lead to a double-free, a daemon crash (leading to denial of service) and potentially remote code execution. Upstream lists several mitigations: - - Servers that don't use EAP or XAuth authentication are not vulnerable to remote attacks. - - Servers that use EAP authentication but delegate it to a RADIUS server and don't request an EAP-Identity themselves are not vulnerable either. However, note that the `eap-radius` plugin parses `Class` and `Filter-Id` attributes as group identities if enabled, in which case a rogue RADIUS server is able to trigger the issue. - - Servers that use IKEv1 with XAuth are not vulnerable unless they use the `xauth-eap` plugin. For the oldstable distribution (bookworm), this problem has been fixed in version 5.9.8-5+deb12u5. For the stable distribution (trixie), this problem has been fixed in version 6.0.1-6+deb13u6. We recommend that you upgrade your strongswan packages.
