Unspecified Vulnerability in NTP

NTP is a network protocol that synchronizes the clocks of two computers by exchanging packets. NTP fails to check symmetric key correspondences when performing packet authentication, allowing a remote attacker to perform impersonation attacks with arbitrary trusted keys...

Multiple Vulnerabilities in Network Time Protocol Daemon Affecting Cisco Products: January 2016

Multiple Cisco products incorporate a version of the Network Time Protocol daemon ntpd package. Versions of this package are affected by one or more vulnerabilities that could allow an unauthenticated, remote attacker to create a denial of service DoS condition or modify the time being advertised...

CVE-2015-7974

NTP 4.x before 4.2.8p6 and 4.3.x before 4.3.90 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key."...

DEBIAN-CVE-2015-7974

NTP 4.x before 4.2.8p6 and 4.3.x before 4.3.90 do not verify peer associations of symmetric keys when authenticating packets, which might allow remote attackers to conduct impersonation attacks via an arbitrary trusted key, aka a "skeleton key."...

CVE-2015-7974

CVE-2015-7974 concerns the NTP reference implementation. The issue arises when authenticated packets are processed: symmetric-key peer associations are not properly verified, potentially enabling a remote attacker to impersonate a trusted peer (skeleton key). Affected are NTP 4.x prior to 4.2.8p6...

ntp: missing check for zero originate timestamp

It was discovered that ntpd as a client did not correctly check the originate timestamp in received packets. A remote attacker could use this flaw to send a crafted packet to an ntpd client that would effectively disable synchronization with the server, or push arbitrary offset/delay measurements...

A client/server for the Network Time Protocol, this program keeps your computer's clock accurate. It was specially designed to support systems with intermittent internet connections, but it also works well in permanently connected environments. It can use also hardware reference clocks, system...

AIX 6.1 TL 9 : ntp (IV79942) (deprecated)

Network Time Protocol NTP is vulnerable to a denial of service, caused by an error in the sntp program. By sending specially crafted NTP packets, a remote attacker from within the local network could exploit this vulnerability to cause the application to enter into an infinite loop. Network Time...

AIX 7.1 TL 3 : ntp (IV79943) (deprecated)

The remote AIX host has a version of Network Time Protocol NTP installed that is affected by the following vulnerabilities : - A divide-by-zero error exists in file include/ntp.h when handling LOGTOD and ULOGTOD macros in a crafted NTP packet. An unauthenticated, remote attacker can exploit this,...
