Title:	Debian: Security Advisory (DSA-5056-1)
Summary:	The remote host is missing an update for the Debian 'strongswan' package(s) announced via the DSA-5056-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'strongswan' package(s) announced via the DSA-5056-1 advisory. Vulnerability Insight: Zhuowei Zhang discovered a bug in the EAP authentication client code of strongSwan, an IKE/IPsec suite, that may allow to bypass the client and in some scenarios even the server authentication, or could lead to a denial-of-service attack. When using EAP authentication (RFC 3748), the successful completion of the authentication is indicated by an EAP-Success message sent by the server to the client. strongSwan's EAP client code handled early EAP-Success messages incorrectly, either crashing the IKE daemon or concluding the EAP method prematurely. End result depend on the used configuration, more details can be found in upstream advisory at [link moved to references](cve-2021-45079).html For the oldstable distribution (buster), this problem has been fixed in version 5.7.2-1+deb10u2. For the stable distribution (bullseye), this problem has been fixed in version 5.9.1-1+deb11u2. We recommend that you upgrade your strongswan packages. For the detailed security status of strongswan please refer to its security tracker page at: [link moved to references] Affected Software/OS: 'strongswan' package(s) on Debian 10, Debian 11. Solution: Please install the updated package(s). CVSS Score: 5.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:N/A:P
