F5 Networks BIG-IP : BIG-IP IPsec IKE peer listener vulnerability (K10133477)

The anonymous IPsec IKE peer configuration object is present and enabled in the default configuration. The settings of the anonymous IPsec IKE peer object allow an arbitrary peer to establish IKE phase 1 without certificate validation or a pre-shared key which may expose phase 2 negotiations to a...

ntp: out-of-bounds references on crafted packet

An out-of-bounds access flaw was found in the way ntpd processed certain packets. An authenticated attacker could use a crafted packet to create a peer association with hmode of 7 and larger, which could potentially although highly unlikely cause ntpd to crash...

stunnel 4.46 < 5.34 Improper Level 4 Peer Certificate Validation Security Bypass

The version of stunnel installed on the remote host is 4.46 or later but prior to 5.34. It is, therefore, affected by a security bypass vulnerability related to the validation of level 4 peer certificates. An unauthenticated, remote attacker can exploit this to have an impact on confidentiality,...

DEBIAN-CVE-2016-4954

The processpacket function in ntpproto.c in ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service peer-variable modification by sending spoofed packets from many source IP addresses in a certain scenario, as demonstrated by triggering an incorrect leap indication...

CVE-2016-4954

The CVE-2016-4954 entry affects ntpd (NTP v4) and is triggered by the process_packet() function in ntp_proto.c, where NTP 4.x versions before 4.2.8p8 can be caused to enter a peer-variable modification state when it receives spoofed packets from multiple sources, demonstrated by an incorrect leap...

The vulnerability of the Pidgin instant messaging system allows a remote attacker to trigger a service denial.

The Pidgin software contains a vulnerability in its component designed to work on the Yahoo! protocol. Exploiting this vulnerability allows a remote attacker to trigger a service failure by creating a P2P message with a length exceeding the maximum allowable buffer size...

ntp: distributed denial of service amplification

CVE-2016-4953 distributed denial of service amplification An attacker who knows the origin timestamp and can send a spoofed packet containing a CRYPTO-NAK to an ephemeral peer target before any other response is sent can demobilize that association. Credit to Miroslav Lichvar of Red Hat -...

Updated ntp packages fix security vulnerabilities

Updated ntp packages fix security vulnerabilities: It is possible to change the time of an ntpd client or deny service to an ntpd client by forcing it to change from basic client/server mode to interleaved symmetric mode. An attacker can spoof a packet from a legitimate ntpd server with an origin...

UBUNTU-CVE-2016-1547

An off-path attacker can cause a preemptible client association to be demobilized in NTP 4.2.8p4 and earlier and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 by sending a crypto NAK packet to a victim client with a spoofed source address of an existing associated peer. This is true even if...
