github.com/moby/sys/user: moby/sys/user: Denial of Service via crafted user or group database files

A flaw was found in the moby/sys/user package. The package does not properly limit memory allocation when parsing Unix-style user and group database files, such as /etc/passwd or /etc/group. An attacker who can supply a specially crafted file can cause excessive memory consumption, leading to a...

AZL-106812 CVE-2026-93326 affecting package moby-engine 25.0.3-20

A build step for a Git source, crafted in a specific way, can bypass some policy validation rules. A malicious build definition can make the repository look like it is coming from a different remote URL than it really is when Git clone is happening. If policy is doing more stricter validation, fo...

Incorrect Behavior Order: Validate Before Canonicalize

Overview Affected versions of this package are vulnerable to Incorrect Behavior Order: Validate Before Canonicalize through the Source.Identifier path in source/git/source.go and source/git/identifier.go. An attacker can make a build appear to use a different Git remote URL than the one in the...

Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value due to unbounded file reads in ReadEntrypoint, dockerIgnorePatterns, and NamedContext.load in frontend/dockerui/config.go and frontend/dockerui/namedcontext.go. An attacker can exhaust buildki...

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value due to unbounded file reads in ReadEntrypoint, dockerIgnorePatterns, and NamedContext.load in frontend/dockerui/config.go and frontend/dockerui/namedcontext.go. An attacker can exhaust buildki...

Improper Validation of Integrity Check Value

Overview Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value via unvalidated image layer DiffIDs through the setBlob and snapshot identity handling in cache/blobs.go, cache/metadata.go, and cache/refs.go. An attacker can cause a later build to mount...

AZL-106824 CVE-2026-93323 affecting package moby-engine 25.0.3-20

The Dockerfile frontend loaded the Dockerfile and .dockerignore files of a build context into memory without a size limit. A build context containing an oversized file could make buildkitd allocate memory proportional to that file, potentially exhausting memory and terminating the daemon, which...

AZL-106815 CVE-2026-93322 affecting package moby-engine 25.0.3-20

A malicious frontend can submit an LLB definition that causes buildkitd to panic and terminate, interrupting all builds running on that daemon...

AZL-106809 CVE-2026-93319 affecting package moby-engine 25.0.3-20

A malicious external BuildKit frontend can send requests using the internal API that can create conditions for a data race that can cause the BuildKit daemon to panic...

AZL-106818 CVE-2026-93318 affecting package moby-engine 25.0.3-20

A malicious image can advertise DiffIDs from another image while containing different layer contents. In affected versions, BuildKit could use the advertised DiffIDs to derive cache and snapshot identity without validating that they matched the actual layer contents. If a BuildKit daemon with...

AZL-106806 CVE-2026-93320 affecting package moby-engine 25.0.3-20

BuildKit may be tricked into performing file actions with special file inodes where regular files are expected. Special files may block operations or, on rootful workers, allow unintended host device access...

Astra Linux – Vulnerability in docker.io-app

Moby is an open-source container framework. In versions prior to 29.5.1, as well as in moby/moby v2 before v2.0.0-beta.14, when a compressed archive was uploaded to a container via PUT /containers/id/archive or piped through docker cp -, the daemon would resolve the decompression binaries such as...
