  "details": "### Impact\n\nThe `limit container paths` directive in `singularity.conf` is intended to allow a system administrator limit the paths from which containers can be run, under setuid mode. Due to incorrect matching of a path string, sibling directories with similar names may incorrectly be allowed.\n\nFor example, the configuration:\n\n```\nlimit container paths = /data/safe\n```\n\nWill also allow containers in `/data/safe-but-unsafe` to be run.\n\n\n### Patches\n\nThis issue is patched in SingularityCE 4.4.2 and SingularityPRO 4.3.9 / 4.1.14\n\n### Workarounds\n\nIf you do not use the `limit container paths` functionality, then this issue does not affect your installation.\n\nIf you do use the `limit container paths` functionality then you must update. Please also review the documented limitations when user namespaces are enabled [1].",
