CVE-2018-5388 – strongSwan VPN Charon Server Buffer Overflow

https://notcve.org/view.php?id=CVE-2018-5388

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 •

CVE-2018-6459

https://notcve.org/view.php?id=CVE-2018-6459

The rsa_pss_params_parse function in libstrongswan/credentials/keys/signature_params.c in strongSwan 5.6.1 allows remote attackers to cause a denial of service via a crafted RSASSA-PSS signature that lacks a mask generation function parameter. La función rsa_pss_params_parse en libstrongswan/credentials/keys/signature_params.c en strong permite que atacantes remotos provoquen una denegación de servicio (DoS) mediante una firma RSASSA-PSS manipulada que carece de un parámetro de función de generación de máscaras. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00047.html https://security.gentoo.org/glsa/201811-16 https://www.strongswan.org/blog/2018/02/19/strongswan-vulnerability-%28cve-2018-6459%29.html • CWE-347: Improper Verification of Cryptographic Signature •

CVE-2017-11185

https://notcve.org/view.php?id=CVE-2017-11185

The gmp plugin in strongSwan before 5.6.0 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted RSA signature. El plugin gmp en strongSwan en versiones anteriores a la 5.6.0 permite que atacantes remotos provoquen una denegación de servicio (desreferencia de puntero NULL y daemon crash) mediante una firma RSA manipulada. • http://www.debian.org/security/2017/dsa-3962 http://www.securityfocus.com/bid/100492 https://www.strongswan.org/blog/2017/08/14/strongswan-vulnerability-%28cve-2017-11185%29.html • CWE-476: NULL Pointer Dereference •

CVE-2017-9022

https://notcve.org/view.php?id=CVE-2017-9022

The gmp plugin in strongSwan before 5.5.3 does not properly validate RSA public keys before calling mpz_powm_sec, which allows remote peers to cause a denial of service (floating point exception and process crash) via a crafted certificate. El plugin gmp en strnogSwan anterior a 5.5.3 no valida adecuadamente las claves públicas RSA tras la llamada mpz_powm_sec, lo que podría permitir a peers remotos causar una denegación de servicio (excepción de punto flotante y cierre inesperado del proceso) a través de un certificado especialmente diseñado. • http://www.debian.org/security/2017/dsa-3866 http://www.securityfocus.com/bid/98760 http://www.ubuntu.com/usn/USN-3301-1 https://www.strongswan.org/blog/2017/05/30/strongswan-vulnerability-%28cve-2017-9022%29.html • CWE-20: Improper Input Validation •
