CVSS: 6.8EPSS: 0%CPEs: 2EXPL: 0CVE-2021-32635 – Action Commands (run/shell/exec) Against Library URIs Ignore Configured Remote Endpoint
https://notcve.org/view.php?id=CVE-2021-32635
Singularity is an open source container platform. In verions 3.7.2 and 3.7.3, Dde to incorrect use of a default URL, `singularity` action commands (`run`/`shell`/`exec`) specifying a container using a `library://` URI will always attempt to retrieve the container from the default remote endpoint (`cloud.sylabs.io`) rather than the configured remote endpoint. An attacker may be able to push a malicious container to the default remote endpoint with a URI that is identical to the URI used by a victim with a non-default remote endpoint, thus executing the malicious container. Only action commands (`run`/`shell`/`exec`) against `library://` URIs are affected. Other commands such as `pull` / `push` respect the configured remote endpoint. • https://github.com/sylabs/singularity/releases/tag/v3.7.4 https://github.com/sylabs/singularity/security/advisories/GHSA-5mv9-q7fq-9394 https://security.gentoo.org/glsa/202107-50 • CWE-20: Improper Input Validation CWE-923: Improper Restriction of Communication Channel to Intended Endpoints •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 1CVE-2021-29499 – Predictable SIF UUID Identifiers
https://notcve.org/view.php?id=CVE-2021-29499
SIF is an open source implementation of the Singularity Container Image Format. The `siftool new` command and func siftool.New() produce predictable UUID identifiers due to insecure randomness in the version of the `github.com/satori/go.uuid` module used as a dependency. A patch is available in version >= v1.2.3 of the module. Users are encouraged to upgrade. As a workaround, users passing CreateInfo struct should ensure the `ID` field is generated using a version of `github.com/satori/go.uuid` that is not vulnerable to this issue. • https://github.com/sylabs/sif/security/advisories/GHSA-4gh8-x3vv-phhg • CWE-330: Use of Insufficiently Random Values •

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') •
