- CVEs with nessus.description==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.
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)
