How to Test & Fix Heart Bleed SSL Vulnerabilities? - Geekflare

May 15, 2014 · The OpenSSL (Heartbleed) vulnerability was independently identified by both Neel Mehta of Google Security on April 1, 2014, and 2 days later by a team of security engineers Riku, Antti, and Matti at Codenomicon.a bThe OpenSSL (Heartbleed) vulnerability has been identified in OpenSSL Versions 1.0.1 through 1.0.1f and 1.0.2-beta1 that contain a flaw in the implementation of the transport layer security/datagram transport layer security (TLS/DTLS) heartbeat functionality. The affected versions of OpenSSL are OpenSSL 1.0.1 through 1.0.1f (inclusive). Subsequent versions (1.0.1g and later) and previous versions (1.0.0 branch and older) are not vulnerable. Installations of the affected versions are vulnerable unless OpenSSL was compiled with -DOPENSSL_NO_HEARTBEATS. Vulnerable program and function 9.0. IBM Rational ClearCase. 9.0.1. IBM Rational ClearCase. 9.0.2. IBM Rational ClearCase. 8.0.1. Not all deployments of Rational ClearCase use OpenSSL in a way that is affected by these vulnerabilities. You are vulnerable if your use of Rational ClearCase includes any of these configurations: A major contributing factor has been that TLS versions 1.1 and 1.2 came available with the first vulnerable OpenSSL version (1.0.1) and security community has been pushing the TLS 1.2 due to earlier attacks against TLS (such as the BEAST). How about operating systems? Apr 21, 2020 · The vulnerability impacts OpenSSL versions 1.1.1d, 1.1.1e and 1.1.1f, and it has been patched with the release of version 1.1.1g. Older versions 1.0.2 and 1.1.0, which no longer receive security updates, are not impacted by the flaw. The security hole was reported to the OpenSSL Project on April 7 by Bernd Edlinger. Dec 09, 2014 · According to this report, the vulnerability in OpenSSL Versions 1.0.1 through 1.0.1f contains a flaw in its implementation of the transport layer security/datagram transport layer security (TLS/DTLS) heartbeat functionality that could disclose private/encrypted information to an attacker.

Jun 05, 2014 · Multiple Cisco products incorporate a version of the OpenSSL package affected by one or more vulnerabilities that could allow an unauthenticated, remote attacker to execute arbitrary code, create a denial of service (DoS) condition, or perform a man-in-the-middle attack. On June 5, 2014, the OpenSSL Project released a security advisory detailing seven distinct vulnerabilities. The

Vulnerability Details. CVEID: CVE-2019-1551 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an overflow in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli.By performing a man-in-the-middle attack, a remote attacker could exploit this vulnerability to obtain sensitive information. SSL 3.0 Protocol Vulnerability and POODLE Attack | CISA All systems and applications utilizing the Secure Socket Layer (SSL) 3.0 with cipher-block chaining (CBC) mode ciphers may be vulnerable. However, the POODLE (Padding Oracle On Downgraded Legacy Encryption) attack demonstrates this vulnerability using web browsers and web servers, which is one of the most likely exploitation scenarios.

OpenSSL Vulnerability - Q&A About What It Means for You

The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel attack. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2b-1 Any OpenSSL internal use of this cipher, including in SSL/TLS, is safe because no such use sets such a long nonce value. However user applications that use this cipher directly and set a non-default nonce length to be longer than 12 bytes may be vulnerable. OpenSSL versions 1.1.1 and 1.1.0 are affected by this issue.
