EulerOS Virtualization 3.0.1.0 : ntp (EulerOS-SA-2019-1557)

According to the versions of the ntp packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - It was found that ntpd did not check whether a Message Authentication Code MAC was present in a received packet when ntpd was...

Denial Of Service (DoS)

Network Time Protocol NTP is vulnerable to denial of service DOS attacks. This occurs in the NTP server's parsing of configuration directives. A remote, authenticated attacker could cause ntpd to crash by sending a crafted message...

Denial Of Service (DoS)

ntp is vulnerable to denial of service. A NULL pointer dereference flaw was found in the way ntpd processed ntpdc reslist commands that queried restriction lists with a large amount of entries. A remote attacker could potentially use this flaw to crash ntpd...

Denial Of Service (DoS)

ntp is vulnerable to denial of service. An incomplete fix for CVE-2014-9750 resulted in improper value length checks in ntpcrypto.c. A packet with particular autokey operations that contained malicious data was not always being completely validated. A remote attacker could use a specially crafted...

Weak Authentication

The Network Time Protocol NTP is used to synchronize a computer's time with a referenced time source. 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...

[SECURITY] Fedora 29 Update: ntp-4.2.8p13-1.fc29

The Network Time Protocol NTP is used to synchronize a computer's time with another reference time source. This package includes ntpd a daemon which continuously adjusts system time and utilities used to query and configure the ntpd daemon. Perl scripts are in the ntp-perl package, ntpdate is in...

[SECURITY] Fedora 28 Update: ntp-4.2.8p13-1.fc28

NTPsec ntpd write_variables Denial of Service (CVE-2019-6445; CVE-2019-8936)

A denial-of-service vulnerability has been reported inN TPsec ntpd. The vulnerability is due to insufficient validation of certain data when parsing a variable in order to write. An attacker could exploit this vulnerability by enticing a target user to open a specially crafted link...

NTPsec ntpd ctl_getitem Out of Bounds Read (CVE-2019-6443)

An out of bounds read vulnerability has been reported in NTPsec ntpd. The vulnerability is due to insufficient validation of the length of a message in a NTP packet. A remote unauthenticated user can exploit this vulnerability by sending a crafted packet to the target server...

The vulnerability of the ctl_getitem method in the ntpd daemon, which is part of the NTP time synchronization protocol, arises from reading data within acceptable buffer limits. This allows a malicious actor to cause a service failure.

The vulnerability of the ctlgetitem method in the ntpd daemon, which implements the NTP synchronization protocol, relates to reading beyond the buffer boundaries in memory. Exploiting this vulnerability could allow a malicious actor to cause service failures by using specially crafted mode 6 Troj...

CVE-2019-6443

An issue was discovered in NTPsec before 1.1.3. Because of a bug in ctlgetitem, there is a stack-based buffer over-read in readsysvars in ntpcontrol.c in ntpd...

CVE-2019-6445

An issue was discovered in NTPsec before 1.1.3. An authenticated attacker can cause a NULL pointer dereference and ntpd crash in ntpcontrol.c, related to ctlgetitem...

CVE-2019-6444

An issue was discovered in NTPsec before 1.1.3. processcontrol in ntpcontrol.c has a stack-based buffer over-read because attacker-controlled data is dereferenced by ntohl in ntpd...
