OpenSSL versions 1.0.1u and prior are prone to privilege elevation vulnerability. The vulnerability exists due to a flaw in the signing function in crypto/ecdsa/ecdsa_ossl.cresulting in a cache-timing attack vulnerability. A malicious user with local access can recover ECDSA P-256 private keys. OpenSSL Security Advisory 20161110
USN-4376-1 fixed several vulnerabilities in OpenSSL. This update provides the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM. Original advisory details: Cesar Pereida García, Sohaib ul Hassan, Nicola Tuveri, Iaroslav Gridin, Alejandro Cabrera Aldaya, and Billy Brumley discovered that OpenSSL incorrectly handled ECDSA signatures. Apr 12, 2020 · CVE-2016-2108 This issue affected versions of OpenSSL prior to April 2015. The bug causing the vulnerability was fixed on April 18th 2015, and released as part of the June 11th 2015 security releases. The security impact of the bug was not known at the time. Apr 22, 2019 · Recently new vulnerabilities like Zombie POODLE, GOLDENDOODLE, 0-Length OpenSSL and Sleeping POODLE were published for websites that use CBC (Cipher Block Chaining) block cipher modes. These vulnerabilities are applicable only if the server uses TLS 1.2 or TLS 1.1 or TLS 1.0 with CBC cipher modes. This only affects you if you are running OpenSSL versions 1.0.1 through 1.0.1f and 1.0.2-beta1, or if you are running software that is using affected versions of the OpenSSL library. The steps to secure your environment against the Heartbleed Bug vulnerability must be done in the following order.
OpenSSL vulnerabilities were disclosed on January 8, 2015 by the OpenSSL Project. This includes "FREAK: Factoring Attack on RSA-EXPORT keys" TLS/SSL client and server vulnerability. OpenSSL is used by MegaRAID Storage Manager. MegaRAID Storage Manager has addressed the applicable CVEs.
OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted Bug is in the OpenSSL's implementation of the TLS/DTLS (transport layer security protocols) heartbeat extension (RFC6520). When it is exploited it leads to the leak of memory contents from the server to the client and from the client to the server. What makes the Heartbleed Bug unique? Jul 09, 2015 · Yesterday, the crew at OpenSSL.org published their highly anticipated ‘high-severity’ vulnerability and patch affecting OpenSSL v1.0.1 & 1.0.2. They had given the security community a heads-up several days ago about the upcoming announcement, and there had been much speculation about the details of the vulnerability. In case you’ve been trapped on a deserted island all day or in a
