Details

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 RPYSUBNETSACCESSED command to the handlesubnetsaccessed function or (2) a RPYCLIENTACCESSES command to the handleclientaccesses function when client logging is disabled, which causes uninitialized data to be included in a reply.
