    CVE-2005-3671

    The Internet Key Exchange version 1 (IKEv1) implementation in Openswan 2 (openswan-2) before 2.4.4, and freeswan in SUSE LINUX 9.1 before 2.04_1.5.4-1.23, allow remote attackers to cause a denial of service via (1) a crafted packet using 3DES with an invalid key length, or (2) unspecified inputs when Aggressive Mode is enabled and the PSK is known, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1.

    CVE-2004-0590

    FreeS/WAN 1.x and 2.x, and other related products including superfreeswan 1.x, openswan 1.x before 1.0.6, openswan 2.x before 2.1.4, and strongSwan before 2.1.3, allows remote attackers to authenticate using spoofed PKCS#7 certificates in which a self-signed certificate identifies an alternate Certificate Authority (CA) and spoofed issuer and subject.

    CVE-2002-0666

    IPSEC implementations including (1) FreeS/WAN and (2) KAME do not properly calculate the length of authentication data, which allows remote attackers to cause a denial of service (kernel panic) via spoofed, short Encapsulating Security Payload (ESP) packets, which result in integer signedness errors.
