NVD Description

Note: Versions mentioned in the description apply only to the upstream openssh-askpass package and not the openssh-askpass package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
