Vulnerability from csaf_redhat - Published: 2017-11-29 03:32 - Updated: 2026-05-13 01:41Summary
Red Hat Security Advisory: tcmu-runner security update
Severity
Moderate
Notes
Topic: An update for tcmu-runner is now available for Red Hat Gluster Storage 3.3.1 for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: The tcmu-runner packages provide a service that handles the complexity of the LIO kernel target's userspace passthrough interface (TCMU). It presents a C plugin API for extension modules that handle SCSI requests in ways not possible or suitable to be handled by LIO's in-kernel backstores.
Security Fix(es):
* A flaw was found in the implementation of CheckConfig method in handler_glfs.so of the tcmu-runner daemon. A local, non-root user with access to the D-Bus system bus could send a specially crafted string to CheckConfig method resulting in various kinds of segmentation fault. (CVE-2017-1000198)
* A NULL pointer dereference flaw was found in the UnregisterHandler method implemented in the tcmu-runner daemon. A local, non-root user with access to the D-Bus system bus could call the UnregisterHandler method with the name of a handler loaded internally in tcmu-runner via dlopen() to trigger DoS. (CVE-2017-1000200)
* A NULL pointer dereference flaw was found in the UnregisterHandler method implemented in the tcmu-runner daemon. A local, non-root user with access to the D-Bus system bus could call UnregisterHandler method with non-existing tcmu handler as paramater to trigger DoS. (CVE-2017-1000201)
* A file information leak flaw was found in implementation of the CheckConfig method in handler_qcow.so of the tcmu-runner daemon. A local, non-root user with access to the D-Bus system bus could use this flaw to leak arbitrary file names which might not be retrievable by non-root user. (CVE-2017-1000199)

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.
