08 Mar 2019 — NTP through 4.2.8p12 has a NULL Pointer Dereference. NTP hasta 4.2.8p12 tiene una desreferencia del puntero NULL. A crafted malicious authenticated mode 6 packet from a permitted network address can trigger a NULL pointer dereference. Note for this attack to work, the sending system must be on an address from which the target ntpd(8) accepts mode 6 packets, and must use a private key that is specifically listed as being used for mode 6 authorization. The ntpd daemon can crash due to the NULL pointer derefer... • https://github.com/snappyJack/CVE-2019-8936 • CWE-476: NULL Pointer Dereference •
