Last modified
CVE-2015-1821 is a vulnerability of currently unknown severity. 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) cmdmon access with a subnet size that is indivisible by four and an address with a nonzero bit in the subnet remainder.. EPSS estimates a 3.44% chance of exploitation in the next 30 days.
