NULL Pointer Dereference

tcmu-runner is vulnerable to NULL pointer dereference. The vulnerability exists 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...

Denial Of Service (DoS)

tcmu-runner is vulnerable to denial of service. A flaw was found in the implementation of CheckConfig method in handlerglfs.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 kin...

RHEL 7 : tcmu-runner (RHSA-2017:3277)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:3277 advisory. The tcmu-runner packages provide a service that handles the complexity of the LIO kernel target's userspace passthrough interface TCMU. It...

tcmu-runner: UnregisterHandler dbus method in tcmu-runner daemon for non-existing handler causes DoS

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...

tcmu-runner: qcow handler opens up an information leak via the CheckConfig D-Bus method

A file information leak flaw was found in implementation of the CheckConfig method in handlerqcow.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...

tcmu-runner: glfs handler allows local DoS via crafted CheckConfig strings

A flaw was found in the implementation of CheckConfig method in handlerglfs.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...

tcmu-runner: UnregisterHandler D-Bus method in tcmu-runner daemon for internal handler causes DoS

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...
