Summary

Red Hat Security Advisory: ipsec-tools security update

Severity

Moderate

Notes

Topic: Updated ipsec-tools packages that fix a denial of service flaw in racoon are now available for Red Hat Enterprise Linux 5. This update has been rated as having moderate security impact by the Red Hat Security Response Team.

Details: The ipsec-tools package is used in conjunction with the IPsec functionality in the linux kernel and includes racoon, an IKEv1 keying daemon. A denial of service flaw was found in the ipsec-tools racoon daemon. It was possible for a remote attacker, with knowledge of an existing ipsec tunnel, to terminate the ipsec connection between two machines. (CVE-2007-1841) Users of ipsec-tools should upgrade to these updated packages, which contain a backported patch that resolves this issue.

CVE-2007-1841

The isakmp_info_recv function in src/racoon/isakmp_inf.c in racoon in Ipsec-tools before 0.6.7 allows remote attackers to cause a denial of service (tunnel crash) via crafted (1) DELETE (ISAKMP_NPTYPE_D) and (2) NOTIFY (ISAKMP_NPTYPE_N) messages.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
