Title:	Debian: Security Advisory (DSA-2903-1)
Summary:	The remote host is missing an update for the Debian 'strongswan' package(s) announced via the DSA-2903-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'strongswan' package(s) announced via the DSA-2903-1 advisory. Vulnerability Insight: An authentication bypass vulnerability was found in charon, the daemon handling IKEv2 in strongSwan, an IKE/IPsec suite. The state machine handling the security association (IKE_SA) handled some state transitions incorrectly. An attacker can trigger the vulnerability by rekeying an unestablished IKE_SA during the initiation itself. This will trick the IKE_SA state to established without the need to provide any valid credential. Vulnerable setups include those actively initiating IKEv2 IKE_SA (like 'clients' or 'roadwarriors') but also during re-authentication (which can be initiated by the responder). Installations using IKEv1 (pluto daemon in strongSwan 4 and earlier, and IKEv1 code in charon 5.x) is not affected. For the oldstable distribution (squeeze), this problem has been fixed in version 4.4.1-5.5. For the stable distribution (wheezy), this problem has been fixed in version 4.5.2-1.5+deb7u3. For the unstable distribution (sid), this problem has been fixed in version 5.1.2-4. We recommend that you upgrade your strongswan packages. Affected Software/OS: 'strongswan' package(s) on Debian 6, Debian 7. Solution: Please install the updated package(s). CVSS Score: 6.4 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:N
