Summary
systemd vulnerabilities
Details
It was discovered that systemd-journald allocated variable-length buffers for certain message fields on the stack. A local attacker could potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2018-16864)
It was discovered that systemd-journald allocated variable-length arrays of objects representing message fields on the stack. A local attacker could potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2018-16865)
An out-of-bounds read was discovered in systemd-journald. A local attacker could potentially exploit this to obtain sensitive information and bypass ASLR protections. (CVE-2018-16866)

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.
