ntp: Multiple buffer overflows via specially-crafted packets

Multiple buffer overflow flaws were discovered in ntpd's cryptorecv, ctlputdata, and configure functions. A remote attacker could use either of these flaws to send a specially crafted request packet that could crash ntpd or, potentially, execute arbitrary code with the privileges of the ntp user...

Important: Red Hat Security Advisory: ntp security update

Updated ntp packages that fix several security issues are now available for Red Hat Enterprise Linux 6 and 7. Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is...

ntp: ntp-keygen uses weak random number generator and seed when generating MD5 keys

It was found that ntp-keygen used a weak method for generating MD5 keys. This could possibly allow an attacker to guess generated MD5 keys that could then be used to spoof an NTP client or server. Note: it is recommended to regenerate any MD5 keys that had explicitly been generated with ntp-keyge...

Updated ntp packages that fix several security issues are now available for Red Hat Enterprise Linux 5. Red Hat Product Security has rated this update as having Important security impact. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available...

ntp: automatic generation of weak default key in config_auth()

It was found that ntpd automatically generated weak keys for its internal use if no ntpdc request authentication key was specified in the ntp.conf configuration file. A remote attacker able to match the configured IP restrictions could guess the generated key, and possibly use it to send ntpdc...

NTP Project Network Time Protocol daemon (ntpd) contains multiple vulnerabilities (Updated)

Overview The NTP Project ntpd version 4.2.7 and pervious versions contain several vulnerabilities. ntp-keygen prior to version 4.2.7p230 also uses a non-cryptographic random number generator when generating symmetric keys. These vulnerabilities may affect ntpd acting as a server or client...

UBUNTU-CVE-2014-9296

The receive function in ntpproto.c in ntpd in NTP before 4.2.8 continues to execute after detecting a certain authentication error, which might allow remote attackers to trigger an unintended association change via crafted packets...

UBUNTU-CVE-2014-9293

The configauth function in ntpd in NTP before 4.2.7p11, when an auth key is not configured, improperly generates a key, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack...

SEIL Series routers vulnerable to denial-of-service (DoS)

Overview SEIL Series routers provided by Internet Initiative Japan Inc. contain a denial-of-service DoS vulnerability due to an issue in processing NTP requests. Note that this vulnerability is different from JVN04895240. Impact By receiving a large volume of NTP request in a short time, the devi...

NTP Reflection Attack

OVERVIEW NCCIC/ICS-CERT has been following the increase in denial-of-service DoS attacks using Network Time Protocol NTP Reflection. This type of attack provides an adversary the ability to generate high volume distributed denial of service DDoS traffic to target web sites or public‑facing device...

Cisco IOS Software and IOS XE Software NTP Access Group Vulnerability

A vulnerability in the implementation of the ntp access-group command in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to bypass the configured Network Time Protocol NTP access group and query the affected NTP-configured server for the time. The...
