An update that solves four vulnerabilities and has one
errata is now available.

Description:

This update for runc fixes the following issues:

Security vulnerabilities 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
