Open Container Initiative umoci before 0.4.7 allows attackers to overwrite arbitrary host paths via a crafted image that causes symlink traversal when "umoci unpack" or "umoci raw unpack" is used. Open Container Initiative umoci versiones anteriores a 0.4.7, permite a atacantes sobrescribir rutas de host arbitrarias por medio de una imagen diseñada que causa un salto de enlace simbólico cuando es usado "umoci unpack" o "umoci raw unpack" • http://www.openwall.com/lists/oss-security/2021/04/06/2 https://github.com/opencontainers/umoci/commit/d9efc31daf2206f7d3fdb839863cf7a576a2eb57 https://github.com/opencontainers/umoci/security/advisories/GHSA-9m95-8hx6-7p9v • CWE-20: Improper Input Validation •
CVSS: 9.3EPSS: 0%CPEs: 4EXPL: 0CVE-2020-15229 – Path traversal and files overwrite with unsquashfs
https://notcve.org/view.php?id=CVE-2020-15229
Singularity (an open source container platform) from version 3.1.1 through 3.6.3 has a vulnerability. Due to insecure handling of path traversal and the lack of path sanitization within `unsquashfs`, it is possible to overwrite/create any files on the host filesystem during the extraction with a crafted squashfs filesystem. The extraction occurs automatically for unprivileged (either installation or with `allow setuid = no`) run of Singularity when a user attempt to run an image which is a local SIF image or a single file containing a squashfs filesystem and is coming from remote sources `library://` or `shub://`. Image build is also impacted in a more serious way as it can be used by a root user, allowing an attacker to overwrite/create files leading to a system compromise, so far bootstrap methods `library`, `shub` and `localimage` are triggering the squashfs extraction. This issue is addressed in Singularity 3.6.4. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00070.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00071.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00009.html https://github.com/hpcng/singularity/blob/v3.6.4/CHANGELOG.md#security-related-fixes https://github.com/hpcng/singularity/commit/eba3dea260b117198fdb6faf41f2482ab2f8d53e https://github.com/hpcng/singularity/pull/5611 https://github.com/hpcng/singularity/security/advisories/GHSA-7gcp-w6ww-2xv9 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

Sylabs Singularity 3.0 through 3.5 has Improper Validation of an Integrity Check Value. Image integrity is not validated when an ECL policy is enforced. The fingerprint required by the ECL is compared against the signature object descriptor(s) in the SIF file, rather than to a cryptographically validated signature.
