Synopsis

The remote openSUSE host is missing a security update.

Description

This update for runc fixes the following issues :

Security vulnerablities addressed :

- CVE-2019-5736: Effectively copying /proc/self/exe during re-exec to avoid write attacks to the host runc binary, which could lead to a container breakout (bsc#1121967)

- CVE-2018-16873: Fix a remote command execution during 'go get -u' (boo#1118897)

- CVE-2018-16874: Fix a directory traversal in 'go get' via curly braces in import paths (boo#1118898)

- CVE-2018-16875: Fix a CPU denial of service issue (boo#1118899)

Other changes and bug fixes :

- Update go requirements to >= go1.10

- Create a symlink in /usr/bin/runc to enable rootless Podman and Buildah.

- Make use of %license macro

- Remove 'go test' from %check section, as it has only ever caused us problems and hasn't (as far as I remember) ever caught a release-blocking issue. Smoke testing has been far more useful. (boo#1095817)

- Upgrade to runc v1.0.0~rc6. Upstream changelog is available from https://github.com/opencontainers/runc/releases/tag/v1.0 .0-rc6

Solution

Update the affected runc packages.
