CVE-2016-10708
sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 15.7%, higher than 97% of all known CVEs. Patch or mitigate before the next change window.
