CVE-2014-9294
util/ntp-keygen.c in ntp-keygen in NTP before 4.2.7p230 uses a weak RNG seed, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 13.0%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
