CVE-2019-18217
ProFTPD before 1.3.6b and 1.3.7rc before 1.3.7rc2 allows remote unauthenticated denial-of-service due to incorrect handling of overly long commands because main.c in a child process enters an infinite loop.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 20.3%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
