Description

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.

Affected configurations

• sylabs singularity (>= 3.1.0 < 3.2.0) • sylabs singularity 3.2.0 • fedoraproject fedora 28 • fedoraproject fedora 29 • fedoraproject fedora 30 • opensuse backports sle-15 • opensuse leap 15.1
