CVE-2001-0376
CVE-2001-0376 affects SonicWALL Tele2 and SOHO firewalls running firmware 6.0.0.0 when using IPsec with IKE pre-shared keys. The root cause is that the implementation supports only 48-byte IKE PSKs instead of the full 128-byte length, reducing the effective key space. This enables a remote attack...
CVE-2001-0284
Buffer overflow in IPSEC authentication mechanism for OpenBSD 2.8 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a malformed Authentication header AH IPv4 option...
CVE-2001-0284
The CVE-2001-0284 entry describes a buffer overflow in the IPSEC authentication mechanism for OpenBSD 2.8 and earlier. The underlying issue is in the IPSEC AH (IPv4 option) processing, allowing remote attackers to cause a denial of service and potentially execute arbitrary commands via a malforme...
Cisco HSRP Weakness/DoS
Hi I was playing with Cisco's HSRP Hot Standby Routing Protocol, and there is a major weakness in that protocol that allow any host in a LAN segment to make a HSRP DoS. Short very explain of HSRP. HSRP uses UDP on port 1985 to multicast address 224.0.0.2, and the authentication is in clear text...
Nortel CES (3DES version) offers false sense of security when using IPSEC
Short summary: Nortel Networks Contivity Extranet Switch CES has a weakness in it's IPSEC key exchange when using 3DES encryption. The 3DES encryption keys are encrypted using single DES during initial key exchange thus reducing cryptographic strength to 56-bit DES level. The weakness affects bot...
CVE-2000-0962
The CVE-2000-0962 entry concerns OpenBSD 2.7 IPSEC, where the implementation mishandles empty AH/ESP packets. This underpins a denial of service when processing such packets, with an impact described as partial availability. The available sources (NVD/CVE records) repeat the same description and ...

Nmap Protocol Scanning DoS against OpenBSD IPSEC
The protocol scanning option -sO in 2.54 Beta releases of nmap results in a remote denial of service against OpenBSD 2.7's IPSEC implementation due to its inability to handle tiny AH/ESP packets. Nmap protocol scans repeatedly cycle through IP protocol version numbers, attempting to elicit ICMP...

CVE-1999-0727
CVE-1999-0727 affects the OpenBSD kernel, where a kernel leak could allow IPsec packets to be sent unencrypted. Documents confirm the root cause is a kernel leak in the OpenBSD kernel, with impact described as partial confidentiality (IPsec traffic could be exposed). The available sources do not ...
