For your online application or server to be secure, SSL/TLS certificates are necessary. While many trustworthy certificate authorities charge a fee for SSL/TLS certificates, it is also feasible to create your own certificate using OpenSSL. Self-signed certificates may nonetheless encrypt your online traffic even if they don’t have the approval of a reputable organization. The […]
The OpenSSL project has rolled out fixes to contain two high-severity flaws in its widely used cryptography library that could result in a denial-of-service (DoS) and remote code execution. The issues, tracked as CVE-2022-3602 and CVE-2022-3786, have been described as buffer overrun vulnerabilities that can be triggered during X.509 certificate verification by supplying a specially-crafted […]
An open-source project called OpenSSL is used to protect communications all across the world and offers simple cryptographic functionality. Simply put, OpenSSL powers the internet. OpenSSL has a number of flaws, but the two that are most well-known are the Heartbleed bug (CVE-2014-0160) and the OpenSSL 1.1.0a vulnerability (CVE-2016-6309). OpenSSL 3.0.7 update to fix Critical […]
OpenSSL is a famous cryptography library that provides an open source implementation of the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. It allows generating RSA private keys and performing encryption and decryption. A critical vulnerability in OpenSSL could allow a threat actor to achieve remote code execution (RCE) on server-side devices. Heap […]
The latest version of the OpenSSL library has been discovered as susceptible to a remote memory-corruption vulnerability on select systems. The issue has been identified in OpenSSL version 3.0.4, which was released on June 21, 2022, and impacts x64 systems with the AVX-512 instruction set. OpenSSL 1.1.1 as well as OpenSSL forks BoringSSL and LibreSSL […]
OpenSSL announced the release of an update to address a severe vulnerability in the library whose exploitation would lead to an infinite loop function and an eventual denial of service (DoS) condition. Although DoS attacks are not the most dangerous hacking variant, they can cause significant business disruption, long-term financial repercussions, and a severe loss […]
Cybersecurity specialists report the detection of two severe vulnerabilities in OpenSSL. According to the report, the successful exploitation of these flaws would allow the execution of attacks that could completely compromise the target system. Below are brief descriptions of the reported failures in addition to their respective identification keys and scores assigned according to the […]
The maintainers of OpenSSL have released a fix for two high-severity security flaws in its software that could be exploited to carry out denial-of-service (DoS) attacks and bypass certificate verification. Tracked as CVE-2021-3449 and CVE-2021-3450, both the vulnerabilities have been resolved in an update (version OpenSSL 1.1.1k) released on Thursday. While CVE-2021-3449 affects all OpenSSL […]

The first round of security updates released in 2018 for OpenSSL patch a total of three vulnerabilities, but none of them appears to be serious, information security training professionals said. OpenSSL versions 1.1.0h and 1.0.2o patch CVE-2018-0739, a denial-of-service (DoS) vulnerability discovered using Google’s OSS-Fuzz service, which has helped find several flaws in OpenSSL in the past […]
Ubuntu users are being urged to update their operating systems to address a handful of recently patched OpenSSL vulnerabilities which affect Ubuntu and its derivatives. Developers with Canonical, the company that oversees the Linux distribution, announced the updates on Tuesday, encouraging users to install the latest OpenSSL package versions depending on which distribution they’re running. The updates […]
What is Openssl? OpenSSL is a an open source project that provides a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It ensures secure communications against attackers from Eavesdropping and MITM attacks. Openssl library includes tools for generating RSA/ECC public and private keys. OpenSSL is written in C, but […]
