Critical: openssl

Issue Overview: The TLS protocol 1.1 and 1.2 and the DTLS protocol 1.0 and 1.2, as used in OpenSSL, OpenJDK, PolarSSL, and other products, do not properly consider timing side-channel attacks on a MAC check requirement during the processing of malformed CBC padding, which allows remote attackers ...

OpenSSL Heartbeat (Heartbleed) Information Leak

This module implements the OpenSSL Heartbleed attack. The problem exists in the handling of heartbeat requests, where a fake length can be used to leak memory data in the response. Services that support STARTTLS may also be vulnerable. The module supports several actions, allowing for scanning,...

Internet Bug Bounty: TLS heartbeat read overrun

A missing bounds check in the handling of the TLS heartbeat extension can be used to reveal up to 64k of memory to a connected client or server. Only 1.0.1 and 1.0.2-beta releases of OpenSSL are affected including 1.0.1f and 1.0.2-beta1. Thanks for Neel Mehta of Google Security for discovering th...

Watchwatch-like Heartbeat Monitor to Replace Passwords

The heart beating in our chests contains in its right atrium a bundle of nerve cells and synapses known as the cardiac pacemaker. The cardiac pacemaker emits electrical impulses that cause the human heart to beat. These electrical impulses and the heart rhythm they produce can be measured by an...

CVE-2013-1213

Cisco NX-OS on the Nexus 1000V does not assign the proper priority to heartbeat messages from a Virtual Ethernet Module VEM to a Virtual Supervisor Module VSM, which allows remote attackers to cause a denial of service false VEM unavailability report via a flood of UDP packets, aka Bug ID...

Cisco Nexus 1000V VSM/VEM Heartbeat Denial of Service Vulnerability

A vulnerability in the Cisco Nexus 1000V could allow an unauthenticated, remote attacker to cause a Virtual Supervisor Module VSM to report a Virtual Ethernet Module VEM as unavailable. The vulnerability is due to insufficient prioritization for VSM/VEM heartbeat messages. An attacker could explo...

CVE-2013-1213: Undefined Security Weakness

PT-2013-2976

Name of the Vulnerable Software and Affected Versions Cisco NX-OS on the Nexus 1000V affected versions not specified Description The issue is related to the insufficient prioritization of heartbeat messages between a Virtual Ethernet Module VEM and a Virtual Supervisor Module VSM. This allows...

OpenSSL TLS 1.1 and 1.2 AES-NI DoS

The AES-NI implementation of OpenSSL 1.0.1c does not properly compute the length of an encrypted message when used with a TLS version 1.1 or above. This leads to an integer underflow which can cause a DoS. The vulnerable function aesnicbchmacsha1cipher is only included in the 64-bit versions of...
