CVSS: 5.0EPSS: 4%CPEs: 1EXPL: 0CVE-2015-3240 – openswan: denial of service via IKE daemon restart when receiving a bad DH gx value
https://notcve.org/view.php?id=CVE-2015-3240
The pluto IKE daemon in libreswan before 3.15 and Openswan before 2.6.45, when built with NSS, allows remote attackers to cause a denial of service (assertion failure and daemon restart) via a zero DH g^x value in a KE payload in a IKE packet. El demonio pluto IKE en libreswan en versiones anteriores a 3.15 y Openswan en versiones anteriores a 2.6.45, cuando ha sido construido con NSS, permite a atacantes remotos causar una denegación de servicio (fallo de aserción y reinicio de demonio) a través de un valor zero DH g^x en un payload KE en un paquete IKE. A flaw was discovered in the way Libreswan's IKE daemon processed IKE KE payloads. A remote attacker could send specially crafted IKE payload with a KE payload of g^x=0 that, when processed, would lead to a denial of service (daemon crash). • http://rhn.redhat.com/errata/RHSA-2015-1979.html http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus.com/bid/77536 http://www.securitytracker.com/id/1033418 https://libreswan.org/security/CVE-2015-3240/CVE-2015-3240.txt https://lists.openswan.org/pipermail/users/2015-August/023401.html https://security.gentoo.org/glsa/201603-13 https://access.redhat.com/security/cve/CVE-2015-3240 https://bugzilla.redhat.com/show_bug.cgi?id= • CWE-189: Numeric Errors CWE-617: Reachable Assertion •

libreswan 3.9 through 3.12 allows remote attackers to cause a denial of service (daemon restart) via an IKEv1 packet with (1) unassigned bits set in the IPSEC DOI value or (2) the next payload value set to ISAKMP_NEXT_SAK. libreswan 3.9 hasta 3.12 permite a atacantes remotos causar una denegación de servicio (reinicio de demonio) a través de un paquete IKEv1 con (1) bits no asignados configurados en el valor IPSEC DOI o (2) el valor del próxima carga útil configurado en ISAKMP_NEXT_SAK. A flaw was discovered in the way Libreswan's IKE daemon processed certain IKEv1 payloads. A remote attacker could send specially crafted IKEv1 payloads that, when processed, would lead to a denial of service (daemon crash). • http://rhn.redhat.com/errata/RHSA-2015-1154.html http://www.securityfocus.com/bid/75392 https://libreswan.org/security/CVE-2015-3204/CVE-2015-3204.txt https://security.gentoo.org/glsa/201603-13 https://access.redhat.com/security/cve/CVE-2015-3204 https://bugzilla.redhat.com/show_bug.cgi?id=1223361 • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •
