CVE-2023-30549 3 Lfprojects, Redhat, Sylabs 3 Apptainer, Enterprise Linux, Singularity 2023-11-25 N/A 7.8 HIGH
Apptainer is an open source container platform for Linux. There is an ext4 use-after-free flaw that is exploitable through versions of Apptainer < 1.1.0 and installations that include apptainer-suid < 1.1.8 on older operating systems where that CVE has not been patched. That includes Red Hat Enterprise Linux 7, Debian 10 buster (unless the linux-5.10 package is installed), Ubuntu 18.04 bionic and Ubuntu 20.04 focal. Use-after-free flaws in the kernel can be used to attack the kernel for denial of service and potentially for privilege escalation. Apptainer 1.1.8 includes a patch that by default disables mounting of extfs filesystem types in setuid-root mode, while continuing to allow mounting of extfs filesystems in non-setuid "rootless" mode using fuse2fs. Some workarounds are possible. Either do not install apptainer-suid (for versions 1.1.0 through 1.1.7) or set `allow setuid = no` in apptainer.conf. This requires having unprivileged user namespaces enabled and except for apptainer 1.1.x versions will disallow mounting of sif files, extfs files, and squashfs files in addition to other, less significant impacts. (Encrypted sif files are also not supported unprivileged in apptainer 1.1.x.). Alternatively, use the `limit containers` options in apptainer.conf/singularity.conf to limit sif files to trusted users, groups, and/or paths, and set `allow container extfs = no` to disallow mounting of extfs overlay files. The latter option by itself does not disallow mounting of extfs overlay partitions inside SIF files, so that's why the former options are also needed.
CVE-2020-25039 2 Opensuse, Sylabs 2 Leap, Singularity 2021-07-21 5.5 MEDIUM 8.1 HIGH
Sylabs Singularity 3.2.0 through 3.6.2 has Insecure Permissions on temporary directories used in fakeroot or user namespace container execution.
CVE-2020-25040 2 Opensuse, Sylabs 2 Leap, Singularity 2021-07-21 6.5 MEDIUM 8.8 HIGH
Sylabs Singularity through 3.6.2 has Insecure Permissions on temporary directories used in explicit and implicit container build operations, a different vulnerability than CVE-2020-25039.
CVE-2021-29499 1 Sylabs 1 Singularity Image Format 2021-05-19 4.0 MEDIUM 7.5 HIGH
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.
CVE-2020-13847 1 Sylabs 1 Singularity 2020-09-18 5.0 MEDIUM 7.5 HIGH
Sylabs Singularity 3.0 through 3.5 lacks support for an Integrity Check. Singularity's sign and verify commands do not sign metadata found in the global header or data object descriptors of a SIF file.
CVE-2020-13845 1 Sylabs 1 Singularity 2020-09-18 5.0 MEDIUM 7.5 HIGH
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.
CVE-2020-13846 1 Sylabs 1 Singularity 2020-09-18 5.0 MEDIUM 7.5 HIGH
Sylabs Singularity 3.5.0 through 3.5.3 fails to report an error in a Status Code.
CVE-2019-11328 1 Sylabs 1 Singularity 2020-08-24 9.0 HIGH 8.8 HIGH
An issue was discovered in Singularity 3.1.0 to 3.2.0-rc2, a malicious user with local/network access to the host system (e.g. ssh) could exploit this vulnerability due to insecure permissions allowing a user to edit files within `/run/singularity/instances/sing/<user>/<instance>`. The manipulation of those files can change the behavior of the starter-suid program when instances are joined resulting in potential privilege escalation on the host.
CVE-2019-19724 1 Sylabs 1 Singularity 2020-07-23 5.0 MEDIUM 7.5 HIGH
Insecure permissions (777) are set on $HOME/.singularity when it is newly created by Singularity (version from 3.3.0 to 3.5.1), which could lead to an information leak, and malicious redirection of operations performed against Sylabs cloud services.
CVE-2018-19295 1 Sylabs 1 Singularity 2019-01-24 7.2 HIGH 7.8 HIGH
Sylabs Singularity 2.4 to 2.6 allows local users to conduct Improper Input Validation attacks.
