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.

For the avoidance of doubt libssl is not vulnerable because explicit parameters are never used. OpenSSL versions 1.1.1, 1.1.0 and 1.0.2 are affected by this issue. (CVE-2019-1547) - OpenSSL 1.1.1 introduced a rewritten random number generator (RNG). This was intended to include protection in the event of a fork() system call in order to ensure OpenSSL 3.0 is the next major version of OpenSSL that is currently in development and includes the new FIPS Object Module. A pre-release version of this is available below. This is for testing only. It should not be used in production. Information and notes about OpenSSL 3.0 are available on the OpenSSL Wiki 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:

Aug 22, 2018 · A vulnerable OpenSSH server would react in two very different ways when this happens. If the username included in the malformed authentication request does not exist, the server responds with

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 OpenSSL Vulnerability | CISA

Apr 09, 2014 · The vulnerability affects the ”heartbeat” extension in TLS 1.2 in OpenSSL, and has been present in the V1.0.1 version since its implementation about 2 years ago. A successful exploitation of the vulnerability leads to inadvertent disclosure of memory on the targeted machine, which can contain confidential information such as session-cookies

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 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.
