    Package : schroot
    CVE ID : CVE-2022-2787

    Julian Gilbey discovered that schroot, a tool allowing users to execute commands in a chroot environment, 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.

    Note that existing chroots and sessions are checked during upgrade, and
    an upgrade is aborted if any future invalid name is detected.

    Problematic session and chroots can be checked before upgrading with the following command:

    schroot --list --all | LC_ALL=C grep -vE '^[a-z]+:[a-zA-Z0-9][a-zA-Z0-9_.-]*$'

    See

    <https://codeberg.org/shelter/reschroot/src/tag/release/reschroot-1.6.13/NEWS#L10-L41>

    for instructions on how to resolve such a situation.

    For the stable distribution (bullseye), this problem has been fixed in
    version 1.6.10-12+deb11u1.

    We recommend that you upgrade your schroot packages.
