Vulnerability from csaf_redhat - Published: 2009-05-18 20:09 - Updated: 2024-11-22 02:43Summary
Red Hat Security Advisory: ipsec-tools security update
Severity
Important
Notes
Topic: An updated ipsec-tools package that fixes multiple security issues is now
available for Red Hat Enterprise Linux 5.
This update has been rated as having important 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. An
unauthenticated, remote attacker could trigger a NULL pointer dereference
that could cause the racoon daemon to crash. (CVE-2009-1574)
Multiple memory leak flaws were found in the ipsec-tools racoon daemon. If
a remote attacker is able to make multiple connection attempts to the
racoon daemon, it was possible to cause the racoon daemon to consume all
available memory. (CVE-2009-1632)
Users of ipsec-tools should upgrade to this updated package, which contains
backported patches to correct these issues. Users must restart the racoon
daemon for this update to take effect.

racoon/isakmp_frag.c in ipsec-tools before 0.7.2 allows remote attackers to cause a denial of service (crash) via crafted fragmented packets without a payload, which triggers a NULL pointer dereference.

Threats
Impact
Important
Multiple memory leaks in Ipsec-tools before 0.7.2 allow remote attackers to cause a denial of service (memory consumption) via vectors involving (1) signature verification during user authentication with X.509 certificates, related to the eay_check_x509sign function in src/racoon/crypto_openssl.c; and (2) the NAT-Traversal (aka NAT-T) keepalive implementation, related to src/racoon/nattraversal.c.

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.
