Bootstrap methods `library`, `shub` and `localimage` trigger a squashfs extraction.\n\n### Patches\n\nThis issue is addressed in Singularity 3.6.4.\n\nAll users are advised to upgrade to 3.6.4 especially if they use Singularity mainly for building image as root user.\n\n### Workarounds\n\nThere is no solid workaround except to temporarily avoid use of unprivileged mode with single file images, in favor of sandbox images instead. Regarding image build, temporarily avoid building from `library` and `shub` sources, and as much as possible use `--fakeroot` or a VM to limit potential impact.\n\n### For more information\n\nGeneral questions about the impact of the advisory / changes made in the 3.6.0 release can be asked in the:\n\n* [Singularity Slack Channel](https://bit.ly/2m0g3lX)\n* [Singularity Mailing
