    Package        : strongswan     CVE ID         : CVE-2026-25075

    Kazuma Matsumoto discovered an integer overflow bug in the EAP-TTLS plugin of     strongSwan, an IKE/IPsec suite.

    The EAP-TTLS plugin doesn't check the length field in the header of     attribute-value pairs (AVPs) tunneled in EAP-TTLS, which can cause an integer     underflow that may lead to a crash. An unauthenticated attacker could exploit     this for a DoS attack by sending a crafted message.

    For the oldstable distribution (bookworm), this problem has been fixed     in version 5.9.8-5+deb12u3.

    For the stable distribution (trixie), this problem has been fixed in     version 6.0.1-6+deb13u4.

    We recommend that you upgrade your strongswan packages.

    For the detailed security status of strongswan please refer to     its security tracker page at:
