Security update for containerd, docker, docker-runc, golang-github-docker-libnetwork, runc
This update for containerd, docker, docker-runc, golang-github-docker-libnetwork, runc fixes the following issues:
Security issues fixed:
- CVE-2018-16875: Fixed a CPU Denial of Service (bsc#1118899).
- CVE-2018-16874: Fixed a vulnerabity in go get command which could allow directory traversal in GOPATH mode (bsc#1118898).
- CVE-2018-16873: Fixed a vulnerability in go get command which could allow remote code execution when executed with -u in GOPATH mode (bsc#1118897).
- 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).
Other changes and bug fixes:
- Update shell completion to use Group: System/Shells.
- Add daemon.json file with rotation logs configuration (bsc#1114832)
- Update to Docker 18.09.1-ce (bsc#1124308) and to to runc 96ec2177ae84. See upstream changelog in the packaged /usr/share/doc/packages/docker/CHANGELOG.md.
- Disable leap based builds for kubic flavor (bsc#1121412).
- Allow users to explicitly specify the NIS domain name of a container (bsc#1001161).
- Update docker.service to match upstream and avoid rlimit problems (bsc#1112980).
- Update go requirements to >= go1.10
- Use -buildmode=pie for tests and binary build (bsc#1048046 and bsc#1051429).
- Remove the usage of 'cp -r' to reduce noise in the build logs.

Описание
RunC allowed additional container processes via 'runc exec' to be ptraced by the pid 1 of the container. This allows the main processes of the container, if running as root, to gain access to file-descriptors of these new processes during the initialization and can lead to container escapes or modification of runC state before the process is fully placed inside the container.

Описание
In Go before 1.10.6 and 1.11.x before 1.11.3, the "go get" command is vulnerable to remote code execution when executed with the -u flag and the import path of a malicious Go package, or a package that imports it directly or indirectly. 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".

Описание
In Go before 1.10.6 and 1.11.x before 1.11.3, the "go get" command is vulnerable to directory traversal when executed with the import path of a malicious Go package which contains curly braces (both '{' and '}' characters). 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.

Описание
The crypto/x509 package of Go before 1.10.6 and 1.11.x before 1.11.3 does not limit the amount of work performed for each chain verification, which might allow attackers to craft pathological inputs leading to a CPU denial of service. Go TLS servers accepting client certificates and TLS clients are affected.

Описание
runc through 1.0-rc6, as used in Docker before 18.09.2 and other products, allows attackers to overwrite the host runc binary (and consequently obtain host root access) by leveraging the ability to execute a command as root within one of these types of containers: (1) a new container with an attacker-controlled image, or (2) an existing container, to which the attacker previously had write access, that can be attached with docker exec. This occurs because of file-descriptor mishandling, related to /proc/self/exe.
