AIX 7.1 TL 2 : ntp (IV74262)

Network Time Protocol NTP Project NTP daemon ntpd is vulnerable to a denial of service, caused by an error when using symmetric key authentication. By sending specially-crafted packets to both peering hosts, an attacker could exploit this vulnerability to prevent synchronization. %NASLMINLEVEL...

AIX 7.1 TL 3 : ntp (IV74261)

The remote AIX host has a version of Network Time Protocol NTP installed that is affected by a denial of service vulnerability due to a flaw in the symmetric-key feature in the receive function in file ntpproto.c when receiving certain invalid packets, which causes state-variable updates to be...

ntp: ntpd accepts unauthenticated packets with symmetric key crypto

It was found that ntpd did not check whether a Message Authentication Code MAC was present in a received packet when ntpd was configured to use symmetric cryptographic keys. A man-in-the-middle attacker could use this flaw to send crafted packets that would be accepted by a client or a peer witho...

ntp: ntp-keygen may generate non-random symmetric keys on big-endian systems

A flaw was found in the way the ntp-keygen utility generated MD5 symmetric keys on big-endian systems. An attacker could possibly use this flaw to guess generated MD5 keys, which could then be used to spoof an NTP client or server...

ntp: drop packets with source address ::1

It was found that because NTP's access control was based on a source IP address, an attacker could bypass source IP restrictions and send malicious control and configuration packets by spoofing ::1 addresses...

ntp: authentication doesn't protect symmetric associations against DoS attacks

A denial of service flaw was found in the way NTP hosts that were peering with each other authenticated themselves before updating their internal state variables. An attacker could send packets to one peer host, which could cascade to other peers, and stop the synchronization process among the...

ntp: vallen in extension fields are not validated

A stack-based buffer overflow was found in the way the NTP autokey protocol was implemented. When an NTP client decrypted a secret received from an NTP server, it could cause that client to crash...

NTP Denial of Service Vulnerability

NTP is a network protocol that synchronizes the clocks of two computers by exchanging packets. NTP has an unspecified security vulnerability that could be exploited by a remote attacker to submit a special request that would crash the service program and cause a denial-of-service attack...
