Quick fix
GHSA-557g-r22w-9wvx — github.com/sylabs/singularity: upgrade to the fixed version with the command below.
go get github.com/sylabs/singularity@v3.2.0Details
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.
