CVE-2015-1798 (GCVE-0-2015-1798)

Vulnerability from cvelistv5

Severity ?

CWE

Summary

The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 4.x before 4.2.8p2 requires a correct MAC only if the MAC field has a nonzero length, which makes it easier for man-in-the-middle attackers to spoof packets by omitting the MAC.
