CVE-2004-0220

CVE-2004-0220 affects OpenBSD isakmpd (OpenBSD 3.4 and older). A malformed Certificate Request payload in ISAKMP can trigger an integer underflow, leading to a failed malloc of a large memory allocation and a denial of service. OpenBSD has issued patches; mitigation is to update/rebuild isakmpd w...

CVE-2004-0222

OpenBSD isakmpd (3.4 and earlier) is affected by memory-leak vulnerabilities in ISAKMP packet processing, allowing remote attackers to exhaust memory and cause a denial-of-service. The issue is described in Rapid7 R7-0018 and CERT/OpenBSD advisories, with references to multiple CVEs (CAN-2004-021...

CVE-2004-0218

OpenBSD isakmpd (OpenBSD 3.4 and earlier) is vulnerable to a remote denial of service via crafted ISAKMP packets with a zero-length payload.
