Security update for runc SUSE Patch security@suse.de SUSE Security Team openSUSE-SU-2019:0208-1 Final 1 1 2019-03-23T11:03:28Z current 2019-03-23T11:03:28Z 2019-03-23T11:03:28Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for runc 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.

Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at https://golang.org/cmd/go/#hdr-Module_aware_go_get). Using custom domains, it's possible to arrange things so that a Git repository is cloned to a folder named ".git" by using a vanity import path that ends with "/.git". If the Git repository root contains a "HEAD" file, a "config" file, an "objects" directory, a "refs" directory, with some work to ensure the proper ordering of operations, "go get -u" can be tricked into considering the parent directory as a repository root, and running Git commands on it. That will use the "config" file in the original Git repository root for its configuration, and if that config file contains malicious commands, they will execute on the system running "go get -u".

Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at https://golang.org/cmd/go/#hdr-Module_aware_go_get). The attacker can cause an arbitrary filesystem write, which can lead to code execution.

Go TLS servers accepting client certificates and TLS clients are affected.

This occurs because of file-descriptor mishandling, related to /proc/self/exe.
