medium Nessus Plugin ID 146460



The remote SUSE host is missing one or more security updates.


This update for containerd, docker, docker-runc, golang-github-docker-libnetwork fixes the following issues :

Security issues fixed :

CVE-2020-15257: Fixed a privilege escalation in containerd (bsc#1178969).

CVE-2021-21284: potential privilege escalation when the root user in the remapped namespace has access to the host filesystem (bsc#1181732)

CVE-2021-21285: pulling a malformed Docker image manifest crashes the dockerd daemon (bsc#1181730)

Non-security issues fixed :

Update Docker to 19.03.15-ce. See upstream changelog in the packaged /usr/share/doc/packages/docker/ This update includes fixes for bsc#1181732 (CVE-2021-21284) and bsc#1181730 (CVE-2021-21285).

Only apply the boo#1178801 libnetwork patch to handle firewalld on openSUSE. It appears that SLES doesn't like the patch. (bsc#1180401)

Update to containerd v1.3.9, which is needed for Docker v19.03.14-ce and fixes CVE-2020-15257. bsc#1180243

Update to containerd v1.3.7, which is required for Docker 19.03.13-ce.

Update to Docker 19.03.14-ce. See upstream changelog in the packaged /usr/share/doc/packages/docker/ CVE-2020-15257 bsc#1180243

Enable fish-completion

Add a patch which makes Docker compatible with firewalld with nftables backend. Backport of (bsc#1178801, SLE-16460)

Update to Docker 19.03.13-ce. See upstream changelog in the packaged /usr/share/doc/packages/docker/ bsc#1176708

Fixes for %_libexecdir changing to /usr/libexec (bsc#1174075)

Emergency fix: %requires_eq does not work with provide symbols, only effective package names. Convert back to regular Requires.

Update to Docker 19.03.12-ce. See upstream changelog in the packaged /usr/share/doc/packages/docker/

Use Go 1.13 instead of Go 1.14 because Go 1.14 can cause all sorts of spurrious errors due to Go returning -EINTR from I/O syscalls much more often (due to Go 1.14's pre-emptive goroutine support).

Add BuildRequires for all -git dependencies so that we catch missing dependencies much more quickly.

Update to libnetwork 55e924b8a842, which is required for Docker 19.03.14-ce. bsc#1180243

Add patch which makes libnetwork compatible with firewalld with nftables backend. Backport of (bsc#1178801, SLE-16460)
