CentOS 6 : ntp (CESA-2015:1459)

Updated ntp packages that fix multiple security issues, several bugs, and add two enhancements are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System CVSS base scores, which give...

ntp, ntpdate security update

CentOS Errata and Security Advisory CESA-2015:1459 Updated ntp packages that fix multiple security issues, several bugs, and add two enhancements are now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerabili...

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: 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: 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 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...

The vulnerability of the microprogramming software of the Cisco Unified Communications Manager allows a remote attacker to gain unauthorized access to the device.

The function for receiving messages in the ntpproto.c file continues to operate even after an error message is displayed. This allows a remote attacker to gain unauthorized access to the device using specially crafted packets...

The vulnerability of the microprogramming software of the Cisco Unified Communications Manager allows a remote attacker to execute arbitrary code.

Buffer overflows occur when performing functions like cryptorecv when Autokey Authentication is used, ctlputdata, and configure. This allows a malicious attacker to execute arbitrary code by sending specially crafted NTP packets...

Vulnerabilities of the Red Hat Enterprise Linux operating system, which allow a remote attacker to compromise the confidentiality, integrity, and accessibility of protected information

The ntp-4.2.6p5 package of the Red Hat Enterprise Linux operating system has multiple vulnerabilities. Exploitation of these vulnerabilities may lead to violations of confidentiality, integrity, and accessibility of protected information. These vulnerabilities can be exploited remotely...
