Debian LTS Advisory DLA-3075-1 [email protected]
https://www.debian.org/lts/security/ Salvatore Bonaccorso

Package : schroot
Version : 1.6.10-6+deb10u1
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 Debian 10 buster, this problem has been fixed in version
1.6.10-6+deb10u1.
We recommend that you upgrade your schroot packages.
For the detailed security status of schroot please refer to its security
tracker page at:
