proot-distro has a Container Isolation Bypass via Crafted Restore Archive

Published Jul 29, 2026 · Updated Jul 29, 2026 · Assigned by GitHub_M

Description

proot-distro is a utility for managing proot containers. Prior to version 5.1.6, proot-distro restore accepted hardlink entries whose linkname referenced another installed container and did not verify that the hardlink source container matched the destination container being restored, allowing a crafted restore archive to copy files between otherwise isolated containers. This issue is fixed in version 5.1.6.
