1 CVE-2018-17540 119 Overflow 2018-10-03 2018-11-27
5.0
None Remote Low Not required None None Partial
The gmp plugin in strongSwan before 5.7.1 has a Buffer Overflow via a crafted certificate.
2 CVE-2018-16152 347 2018-09-26 2018-12-19
5.0
None Remote Low Not required None Partial None
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.
3 CVE-2018-16151 347 2018-09-26 2018-12-19
5.0
None Remote Low Not required None Partial None
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 after the encoded algorithm OID during PKCS#1 v1.5 signature verification. Similar to the flaw in the same version of strongSwan regarding digestAlgorithm.parameters, 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.
4 CVE-2018-10811 665 DoS 2018-06-19 2018-11-27
5.0
None Remote Low Not required None None Partial
strongSwan 5.6.0 and older allows Remote Denial of Service because of Missing Initialization of a Variable.
5 CVE-2018-5388 787 DoS 2018-05-31 2019-10-09
4.0
None Remote Low Single system None None Partial
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.
