Schroot before 1.6.13 had too permissive rules on chroot or session names, allowing a denial of service on the schroot service for all users that may start a schroot session.
Weakness
The product does not preserve permissions or incorrectly preserves permissions when copying, restoring, or sharing objects, which can cause them to have less restrictive permissions than intended.
