Updated docker packages fix security vulnerabilities

Publication date: 19 Oct 2018
Type: security
Affected Mageia releases : 6
CVE: CVE-2017-14992 , CVE-2017-16539 , CVE-2018-10892


Updated docker packages fix security vulnerabilities:

Lack of content verification in docker allowed a remote attacker to cause
a Denial of Service via a crafted image layer payload, aka gzip bombing

The DefaultLinuxSpec function in oci/defaults.go docker did not block
/proc/scsi pathnames, which allowed 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 (CVE-2017-16539).

Container breakout without selinux in enforcing mode (CVE-2018-10892).

The docker package has been updated to version 18.06.1 to fix these issues
and other bugs.

Also, the golang package was updated to version 1.11.1 to be able to build
the update docker software.

Additionally, the docker-containerd and opencontainers-runc packages have
been updated to work with the updated docker package.
