    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.
