Summary

Red Hat Security Advisory: freeradius security update

Severity

Moderate

Notes

Topic: Updated freeradius packages that fix a number of denial of service vulnerabilities as well as minor bugs are now available for Red Hat Enterprise Linux 3.

Details: FreeRADIUS is a high-performance and highly configurable free RADIUS server designed to allow centralized authentication and authorization for a network. A number of flaws were found in FreeRADIUS versions prior to 1.0.1. An attacker who is able to send packets to the server could construct carefully constructed packets in such a way as to cause the server to consume memory or crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-0938, CAN-2004-0960, and CAN-2004-0961 to these issues. Users of FreeRADIUS should update to these erratum packages that contain FreeRADIUS 1.0.1, which is not vulnerable to these issues and also corrects a number of bugs.

CVE-2004-0938

FreeRADIUS before 1.0.1 allows remote attackers to cause a denial of service (server crash) by sending an Ascend-Send-Secret attribute without the required leading packet.

CVE-2004-0960

FreeRADIUS before 1.0.1 allows remote attackers to cause a denial of service (core dump) via malformed USR vendor-specific attributes (VSA) that cause a memcpy operation with a -1 argument.

CVE-2004-0961

Memory leak in FreeRADIUS before 1.0.1 allows remote attackers to cause a denial of service (memory exhaustion) via a series of Access-Request packets with (1) Ascend-Send-Secret, (2) Ascend-Recv-Secret, or (3) Tunnel-Password attributes.

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.
