CVE-2016-3697

libcontainer/user/user.go in runC before 0.1.0, as used in Docker before 1.11.2, improperly treats a numeric UID as a potential username, which allows local users to gain privileges via a numeric username in the password file in a container.

libcontainer/user/user.go in runC before 0.1.0, as used in Docker before 1.11.2, improperly treats a numeric UID as a potential username, which allows local users to gain privileges via a numeric username in the password file in a container.

GetExecUser in the github.com/opencontainers/runc/libcontainer/user package will improperly interpret numeric UIDs as usernames. If the method is used without verifying that usernames are formatted as expected, it may allow a user to gain unexpected privileges.

Updated docker packages fix security vulnerability:

It was found that Docker would launch containers under the specified UID instead of a username. An attacker able to launch a container could use this flaw to escalate their privileges to root within the launched container (CVE-2016-3697).

These are all security issues fixed in the docker-1.12.3-4.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the docker-stable-24.0.9_ce-15.1 package on the GA media of openSUSE Tumbleweed.

docker was updated to fix one security issue.

This security issue was fixed:

• CVE-2016-3697: Potential privilege escalation via confusion of usernames and UIDs (bsc#976777).

This update for docker-stable fixes the following issues:

• Include historical changelog data from before the docker-stable fork. The initial changelog entry did technically provide all the necessary information, but our CVE tracking tools do not understand how the package is forked and so it seems that this package does not include fixes for ~12 years of updates. So, include a copy of the original package's changelog up until the fork point. (bsc#1250596)

• Remove git-core recommends on SLE. Most SLE systems have installRecommends=yes by default and thus end up installing git with Docker. bsc#1250508

  This feature is mostly intended for developers ('docker build git://') so most users already have the dependency installed, and the error when git is missing is fairly straightforward (so they can easily figure out what they need to install).

• Backport https://github.com/moby/moby/pull/48517. bsc#1247362

• Update to docker-buildx v0.25.0. Upstream changelog: https://github.com/docker/buildx/releases/tag/v0.25.0

• Do not try to inject SUSEConnect secrets when in Rootless Docker mode, as Docker does not have permission to access the host zypper credentials in this mode (and unprivileged users cannot disable the feature using /etc/docker/suse-secrets-enable.) bsc#1240150

• Initial docker-stable fork, forked from Docker 24.0.7-ce release (packaged on 2024-02-14). The original changelog is included below for historical reference.
