Test ID:	1.3.6.1.4.1.25623.1.0.702665
Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DSA-2665-1)
Summary:	The remote host is missing an update for the Debian 'strongswan' package(s) announced via the DSA-2665-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'strongswan' package(s) announced via the DSA-2665-1 advisory. Vulnerability Insight: Kevin Wojtysiak discovered a vulnerability in strongSwan, an IPsec based VPN solution. When using the OpenSSL plugin for ECDSA based authentication, an empty, zeroed or otherwise invalid signature is handled as a legitimate one. An attacker could use a forged signature to authenticate like a legitimate user and gain access to the VPN (and everything protected by this). While the issue looks like CVE-2012-2388 (RSA signature based authentication bypass), it is unrelated. For the stable distribution (squeeze), this problem has been fixed in version 4.4.1-5.3. For the testing distribution (wheezy), this problem has been fixed in version 4.5.2-1.5+deb7u1. For the unstable distribution (sid), this problem has been fixed in version 4.6.4-7. 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: 4.9 CVSS Vector: AV:N/AC:M/Au:S/C:P/I:P/A:N
