CVE-2013-6466

Summary (CVE-2013-6466) Openswan 2.6.39 and earlier, when used in some devices (e.g., mGuard firmware 8.0.0–8.5.1), is vulnerable to a remote denial of service via crafted IKEv2 payloads that trigger a NULL pointer dereference in the IKE daemon. The issue allows an attacker to cause the Pluto/IKE...

CVE-2019-10155

The CVE-2019-10155 issue in Libreswan arises from processing IKEv1 informational exchange packets that are encrypted/integrity protected with the IKE SA keys but where the receiver failed to verify the integrity check value. Affected versions are before 3.29. The vulnerability could allow a recip...

CVE-2013-2053

CVE-2013-2053 is a remote, buffer overflow vulnerability in the Openswan 2.6.x codebase (atodn()) that can be triggered when Opportunistic Encryption is enabled and the peer’s DNS PTR record is attacker-controlled. An adversary could cause the pluto IKE daemon to crash and, in some cases, execute...

CVE-2009-0790

OpenSwan/StrongSwan pluto IKE daemon vulnerable to denial of service via crafted DPD packets (R_U_THERE, R_U_THERE_ACK) that trigger a NULL pointer dereference due to inconsistent ISAKMP/phase2 state. Affected: Openswan/Strongswan IPsec implementations listed in CVE-2009-0790 with vulnerable rang...

CVE-2009-2185

CVE-2009-2185 affects the OpenSwan/StrongSwan IPSec implementations via the pluto IKE daemon. The ASN.1 parser in pluto could crash when processing crafted X.509 certificates (specifically crafted RDNs, UTCTIME, or GENERALIZEDTIME strings), producing a denial of service. Affected products and ver...

CVE-2011-3380

CVE-2011-3380 affects Openswan 2.6.29–2.6.35, allowing remote denial of service via a NULL pointer dereference in the pluto IKE daemon when handling an ISAKMP message with an invalid KEY_LENGTH attribute. The issue arises from improper error handling for that attribute, leading to a crash. Severa...

CVE-2011-4073

Openswan pluto IKE daemon (versions 2.3.0–2.6.36) is affected by a use-after-free in the cryptographic helper handler. This remote authenticated vulnerability can crash the daemon (DoS) via vectors in quick_outI1_continue and quick_outI1. A patch exists in Openswan 2.6.37+; upgrade to mitigate. I...

CVE-2008-4190

CVE-2008-4190 stems from Openswan’s IPsec livetest tool. The vulnerability is a local privilege escalation via a symlink attack on temporary files (ipseclive.conn and ipsec.olts.remote.log), allowing local users to overwrite arbitrary files and execute code. Affected products/versions: Openswan 2...

CVE-2005-3671

CVE-2005-3671 affects OpenSwan 2.x (pre-2.4.4) and Freeswan in SUSE Linux 9.1 (before 2.04_1.5.4-1.23). The vulnerability allows a remote attacker to cause a Denial of Service by processing specially crafted ISAKMP/IKEv1 data: (1) a crafted packet using 3DES with an invalid key length, or (2) uns...

CVE-2010-3302

Openswan client (versions 2.6.25–2.6.28) is affected by two buffer overflow flaws in xauth.c and in processing Cisco gateway banners, enabling remote authenticated gateways to potentially execute arbitrary code or cause a denial of service via long cisco_dns_info or cisco_domain_info data. Public...

CVE-2010-3753

CVE-2010-3753 affects the Openswan client (xauth.c) in OpenSwan 2.6.26–2.6.28, where remote authenticated gateways can trigger command execution via shell metacharacters in the Cisco_banner/server_banner field. The root cause is improper input handling in the banner field, enabling arbitrary code...

CVE-2010-3308

Openswan exposure CVE-2010-3308 (and CVE-2010-3302) affects the Openswan client 2.6.26–2.6.28, specifically in the XAUTH handling (programs/pluto/xauth.c) and the Cisco gateway banner/server_banner field. A remote attacker with gateway access could cause arbitrary code execution or a denial of se...

CVE-2010-3752

The CVE entry concerns Openswan, specifically the client-side xauth processing in openswan 2.6.25–2.6.28, where remote authenticated gateways could cause remote code execution via shell metacharacters embedded in Cisco-related data fields (cisco_dns_info and cisco_domain_info). Public references ...

CVE-2005-0162

Openswan pluto vulnerability (CVE-2005-0162): stack-based buffer overflow in get_internal_addresses in Openswan 1.x prior to 1.0.9 and 2.x prior to 2.3.0 when built with XAUTH and PAM. Remote authenticated attackers could execute arbitrary code. Affects the pluto component; exploitation context m...

CVE-2018-15836

CVE-2018-15836 affects Openswan before 2.6.50.1. In verify_signed_hash() (lib/liboswkeys/signatures.c), the RSA PKCS#1 v1.5 padding value is not verified during signature verification, enabling signature forgery when small public exponents are used. IKEv2 signature verification is affected when R...
