In verify_emsa_pkcs1_signature() in gmp_rsa_public_key.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data in the digestAlgorithm.parameters field during PKCS#1 v1.5 signature verification. Consequently, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation when only an RSA signature is used for IKEv2 authentication. This is a variant of CVE-2006-4790 and CVE-2014-1568. En verify_emsa_pkcs1_signature() en gmp_rsa_public_key.c en el plugin gmp en strongSwan en versiones 4.x y 5.x anteriores a la 5.7.0, la implementación RSA basada en GMP no rechaza los datos sobrantes en el campo digestAlgorithm.parameters durante la verificación de firmas PKCS#1 v1.5. En consecuencia, un atacante remoto puede falsificar firmas cuando se emplean pequeños exponentes públicos, lo que podría conducir a una suplantación cuando solo se emplea una firma RSA para la autenticación IKEv2. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00077.html http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00047.html https://lists.debian.org/debian-lts-announce/2018/09/msg00032.html https://security.gentoo.org/glsa/201811-16 https://usn.ubuntu.com/3771-1 https://www.debian.org/security/2018/dsa-4305 https://www.strongswan.org/blog/2018/09/24/strongswan-vulnerability-%28cve-20 • CWE-347: Improper Verification of Cryptographic Signature •

In stroke_socket.c in strongSwan before 5.6.3, a missing packet length check could allow a buffer underflow, which may lead to resource exhaustion and denial of service while reading from the socket. En stroke_socket.c en strongSwan en versiones anteriores a la 5.6.3, la ausencia de comprobaciones de la longitud de los paquetes podría permitir un desbordamiento del búfer, lo que puede conducir al agotamiento del recurso y a la denegación de servicio mientras se lee desde el socket. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00077.html http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00047.html http://packetstormsecurity.com/files/172833/strongSwan-VPN-Charon-Server-Buffer-Overflow.html http://www.kb.cert.org/vuls/id/338343 http://www.securityfocus.com/bid/104263 https://git.strongswan.org/?p=strongswan.git%3Ba=commitdiff%3Bh=0acd1ab4 https://security.gentoo.org/gls • CWE-124: Buffer Underwrite ('Buffer Underflow') CWE-787: Out-of-bounds Write •
