krb5 vulnerabilities
Details
It was discovered that Kerberos incorrectly handled certain memory operations. A remote attacker could possibly use this issue to cause Kerberos to consume memory,leading to a denial of service. (CVE-2024-26458, CVE-2024-26461)
It was discovered that Kerberos incorrectly handled certain memory operations. A remote attacker could possibly use this issue to cause Kerberos to consume memory,leading to a denial of service. This issue only affected Ubuntu 24.04 LTS. (CVE-2024-26462)
It was discovered that the Kerberos kadmind daemon incorrectly handled log files when incremental propagation was enabled. An authenticated attacker could use this issue to cause kadmind to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2025-24528)

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.
