Vulnerability from osv_openeuler – Published: 2025-02-14 11:08 – Updated: 2026-08-06 11:08 – Source website

Summary

krb5 security update

Details

Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography.

Security Fix(es):

In MIT krb5 release 1.7 and later with incremental propagation enabled, an authenticated attacker can cause kadmind to write beyond the end of the mapped region for the iprop log file, likely causing a process crash.(CVE-2025-24528)

Severity

6.5 (Medium)

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.
