ALSA-2026:69961 — Important: podman security update

Affected: AlmaLinux:9: podman, AlmaLinux:9: podman-docker, AlmaLinux:9: podman-plugins, AlmaLinux:9: podman-remote, AlmaLinux:9: podman-tests

The podman tool manages pods, container images, and containers. It is part of the libpod library, which is for applications that use container pods. Container pods is a concept in Kubernetes.

Security Fix(es):

* podman: Go encoding/asn1: Denial of Service via excessive recursion in Unmarshal (CVE-2026-33818) * podman: golang net/url: Denial of Service from quadratic complexity in path resolution (CVE-2026-56860) * podman: Go: Denial of Service via XML decoding recursion depth issue (CVE-2026-56859) * podman: Go html/template: Cross-Site Scripting via pathological input (CVE-2026-56858) * podman: Golang crypto/tls: Denial of Service via indefinite KeyUpdate messages (CVE-2026-56862) * podman: Quadlet install --replace non-truncating write retains removed host-access directives (CVE-2026-19730) * podman: golang.org/x/crypto/ssh: Denial of Service via resource leak from unsolicited SSH responses (CVE-2026-39830) * podman: Go net/[http:](http:) Unencrypted HTTP/2 connections vulnerable to Denial of Service (CVE-2026-56853) * podman: moby/go-archive: Arbitrary file write via link following in tar extraction (CVE-2026-17106)

The tar extraction routines in moby/go-archive (Unpack, UnpackLayer, Untar/UntarUncompressed, and the ApplyLayer helpers) do not confine filesystem operations to the destination directory. The extractor decides where each archive entry lands using lexical string checks and then performs the filesystem operation on a path that is resolved by the OS, so links introduced by the archive can be followed out of the destination directory. An attacker who controls the contents of an archive can create or overwrite files at arbitrary paths writable by the extracting process.

GHSA-hfg8-hc9c-6c3h — moby/go-archive: Crafted tar archive can write outside the extraction directory

Affected: Go: github.com/moby/go-archive

### Summary The tar extraction routines in `moby/go-archive` (`Unpack`, `UnpackLayer`, `Untar`/`UntarUncompressed`, and the `ApplyLayer` helpers) do not confine filesystem operations to the destination directory. A crafted archive can create or overwrite files **outside** the intended destination.

### Details The extractor decides where each archive entry lands using lexical string checks and then performs the filesystem operation on a path that is resolved by the OS, so a links introduced by the archive can be followed out of the destination directory.

### Impact An attacker who controls the contents of archive can create or overwrite files at arbitrary paths writable by the extracting process.

### Workarounds Only extract trusted archives.
