Note that Singularity 3.6.0 uses a new signature format that is necessarily incompatible with Singularity < 3.6.0 - e.g. Singularity 3.5.3 cannot verify containers signed by 3.6.0.\n\nVersion 3.6.0 includes a `--legacy-insecure` flag for the `singularity verify` command, that will perform verification of the older, and insecure, legacy signatures for compatibility with existing containers. This does not guarantee that containers have not been modified since signing, due to other issues in the legacy signature format.\n\n### Workarounds\n\nIf you are unable to update to 3.6.0 ensure that you do not rely on the return code of `singularity verify --all / -a` as an indicator of trust in a container.\n\nNote that other issues in the sign/verify implementation in Singularity < 3.6.0 allow additional means to introduce malicious behavior to a signed container.\n\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 List](https://groups.google.com/a/lbl.gov/forum/??sdf%7Csort:date#!forum/singularity)\n\nAny sensitive

Thus, it is trivial to craft an arbitrary payload which will be permitted to run, even if the attacker does not have access to the private key associated with the fingerprint(s) configured in the ECL.\n\n### Patches\n\nThese issues are addressed in Singularity 3.6.0.\n\nAll users are advised to upgrade to 3.6.0.

This does not guarantee that containers have not been modified since signing, due to other issues in the legacy signature format. The option should be used only to temporarily ease the transition to containers signed with the new 3.6.0 signature format.\n\n### Workarounds\n\nThis issue affects any installation of Singularity configured to use the Execution Control List (ECL) functionality.
