Tcmu Runner
Monthly
In Open-iSCSI tcmu-runner 1.3.x, 1.4.x, and 1.5.x through 1.5.2, xcopy_locate_udev in tcmur_cmd_handler.c lacks a check for transport-layer restrictions, allowing remote attackers to read or write. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, low attack complexity. This Path Traversal vulnerability could allow attackers to access files and directories outside the intended path.
The tcmu-runner daemon in tcmu-runner version 1.0.5 to 1.2.0 is vulnerable to a local denial of service attack. Rated medium severity (CVSS 5.5), this vulnerability is low attack complexity.
tcmu-runner version 1.0.5 to 1.2.0 is vulnerable to a dbus triggered NULL pointer dereference in the tcmu-runner daemon's on_unregister_handler() function resulting in denial of service. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity.
tcmu-runner version 0.91 up to 1.20 is vulnerable to information disclosure in handler_qcow.so resulting in non-privileged users being able to check for existence of any file with root privileges. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
tcmu-runner daemon version 0.9.0 to 1.2.0 is vulnerable to invalid memory references in the handler_glfs.so handler resulting in denial of service. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. This Buffer Overflow vulnerability could allow attackers to corrupt memory to execute arbitrary code or crash the application.
