CWE-200  (opens in a new tab)

How to fix?

Upgrade Debian:unstable chrony to version 1.29-1 or higher.

NVD Description

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

cmdmon.c in Chrony before 1.29 allows remote attackers to obtain potentially sensitive information from stack memory via vectors related to (1) an invalid subnet in a RPY_SUBNETS_ACCESSED command to the handle_subnets_accessed function or (2) a RPY_CLIENT_ACCESSES command to the handle_client_accesses function when client logging is disabled, which causes uninitialized data to be included in a reply.
