NVD Description

Note: Versions mentioned in the description apply only to the upstream bubblewrap package and not the bubblewrap package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

A flaw was found in bubblewrap. During sandbox setup, creating files or directories under the new root can follow a parent symlink onto the host via /oldroot, writing attacker-chosen paths outside the sandbox as the launching user. This happens before the sandboxed process starts. This issue is GHSA-pxhw-h44j-8pfx. It is fixed in bubblewrap 0.12.0.
