CVE-2013-2944 [MEDIUM] CVE-2013-2944 strongswan: ECDSA signature flaw
CVE-2013-2944 strongswan: ECDSA signature flaw
A security flaw was found in the way OpenSSL plug-in of strongSwan, an open-source IPsec-based VPN solution, performed ECDSA signature verificationin certain cases (empty, zeroed or otherwise invalid signature was treated as valid one previously). A remote attacker could provide a forged signature and / or certificate, leading to their ability to be successfully authenticated as legitimate user for particular service.
