A flaw was found in chrony versions before 3.5.1 when creating the PID file under the /var/run/chrony folder. Rated medium severity (CVSS 6.0), this vulnerability is low attack complexity.
chrony before 1.31.2 and 2.x before 2.2.1 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, no authentication required. Public exploit code available.
chrony before 1.31.1 does not initialize the last "next" pointer when saving unacknowledged replies to command requests, which allows remote authenticated users to cause a denial of service. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity.
Heap-based buffer overflow in chrony before 1.31.1 allows remote authenticated users to cause a denial of service (chronyd crash) or possibly execute arbitrary code by configuring the (1) NTP or (2). Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity.
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. Rated medium severity (CVSS 5.0), this vulnerability is remotely exploitable, low attack complexity. This Exposure of Sensitive Information vulnerability could allow attackers to access sensitive data that should not be disclosed.
Multiple integer overflows in pktlength.c in Chrony before 1.29 allow remote attackers to cause a denial of service (crash) via a crafted (1) REQ_SUBNETS_ACCESSED or (2) REQ_CLIENT_ACCESSES command. Rated medium severity (CVSS 5.0), this vulnerability is remotely exploitable, low attack complexity.
