CVE-2020-14367 2 Fedoraproject, Tuxfamily 2 Fedora, Chrony 2020-09-09 3.6 LOW 6.0 MEDIUM
A flaw was found in chrony versions before 3.5.1 when creating the PID file under the /var/run/chrony folder. The file is created during chronyd startup while still running as the root user, and when it's opened for writing, chronyd does not check for an existing symbolic link with the same file name. This flaw allows an attacker with privileged access to create a symlink with the default PID file name pointing to any destination file in the system, resulting in data loss and a denial of service due to the path traversal.
CVE-2015-1853 1 Tuxfamily 1 Chrony 2019-12-17 4.0 MEDIUM 6.5 MEDIUM
chrony before 1.31.1 does not properly protect state variables in authenticated symmetric NTP associations, which allows remote attackers with knowledge of NTP peering to cause a denial of service (inability to synchronize) via random timestamps in crafted NTP data packets.
