CVE-2017-16539 Open this link in a new tabHow to fix?
Upgrade Debian:11 docker.io to version 1.13.1~ds3-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream docker.io package and not the docker.io package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
The DefaultLinuxSpec function in oci/defaults.go in Docker Moby through 17.03.2-ce does not block /proc/scsi pathnames, which allows attackers to trigger data loss (when certain older Linux kernels are used) by leveraging Docker container access to write a "scsi remove-single-device" line to /proc/scsi/scsi, aka SCSI MICDROP.
