CVE-2015-1821

CVE-2015-1821 affects the chrony project (chronyd/chronyc). The issue is an out-of-bounds write flaw in how chrony stores certain addresses when configuring NTP or cmdmon access, triggered by a subnet size not divisible by four and an address with a nonzero bit in the subnet remainder. This can a...

CVE-2015-1822

Chrony CVE-2015-1822 affects chrony before 1.31.1, where the last “next” pointer is not initialized when saving unacknowledged replies to authenticated command requests. This uninitialized pointer can cause a denial of service (daemon crash) and may allow arbitrary code execution under heavy comm...
