with a lot of security budgets must have been checked many times. Everyone wants to be lazy and hopes that others will do the inspection work, as a result, no one has completed all the security checks." He said that the major vulnerabilities found in the most commonly used tools this year indicate that hackers have begun to search for vulnerabilities that have been ignored for a long time in old software. In many cases, this will have astonishing consequences. Now let's talk about the security

vulnerabilities" For enterprises, many key businesses require the support of enterprise software. If the software applied by the enterprise has a critical vulnerability, it will cause incalculable losses to the enterprise. In this article, we will talk about the fatal enterprise software vulnerabilities in the past year. Heartbleed This "heartbleed" vulnerability was first exposed in last April. It allows

September 25 News from Beijing time, Linux users today got a "surprise"! The Red Hat security team found a cryptic and dangerous security flaw in a bash shell that is widely used in Linux. The vulnerability is known as "Bash Bug" or "Shellshock".When the user is properly accessed, the vulnerability allows the attacker's code to execute as if it were in the shell, which opens the door for a variety of attacks. And, worse, the vulnerability has been around Linux for a long time, so patching a Linu

OpenSSL is a recently updated version and that your client also uses the latest software. Heartbleed (Heart bleed) Hearbleed is a security vulnerability found in the April 2014 OpenSSL cipher Library, which is widely used in the implementation of the Transport Layer (TLS) protocol. Heartbleed may be used regardless of whether or not a vulnerable OpenSSL is used, such as on a server or client. It is in th

CVE-2014-0160 vulnerability background OpenSSL released a Security Bulletin on April 7, 2014, in OpenSSL1.0.1 there is a serious vulnerability (CVE-2014-0160 ). The OpenSSL Heartbleed module has a BUG. The problem lies in the heartbeat section in the ssl/dl_both.c file. When attackers construct a special data packet, if the user's heartbeat packet cannot provide enough data, the memcpy function will output the data recorded in SSLv3 directly, this vul

Why is the Bash Security Vulnerability a global server attack? On September 24, 2014, Bash experienced a critical security vulnerability, numbered CVE-2014-6271, that could cause remote attackers to execute arbitrary code on the affected system. GNU Bash is a Unix Shell compiled for the GNU program. It is widely used in Linux systems. Its initial function is only a simple terminal-based command interpreter. This means that at least 1.5 million of Hosts around the world will be affected, and And

Security Control of open-source software As shown in OpenSSL heartbleed, if you do not know the code in your product, it may cause serious security threats or even prolonged remedial work. On the contrary, if you are familiar with open-source components and their versions in the project, you can quickly respond and fix them in time.

main one is that the plan for releasing security fixes will be announced first (along with its severity ), A post will be posted to publish the specific schedule on the OpenSSL homepage, but the nature of the fix will not be made public until it is released. However, "If the updates contain very serious problems, we will also send more details and patches in advance." The basic consideration is that we need to notify users of additional issues, it takes several days for the OpenSSL operating sy

OpenSSL will release security patches tomorrow to fix undisclosed 0-day high-risk Vulnerabilities OpenSSL officially issued a vulnerability warning, reminding the system administrator to prepare for OpenSSL upgrade. The latest version of OpenSSL will be released on April 9, July 9 (this Thursday) to fix an undisclosed high-risk vulnerability. Many security experts speculate that this high-risk vulnerability may be another "heartbleed" vulnerability "

High-risk bash vulnerabilities are detected. Be careful with your server! Background: On July 15, September 25, Beijing time, a Linux User got another"Surprise"! The Red Hat security team found a hidden and dangerous security vulnerability in the bash shell widely used in Linux. This vulnerability is called "bash bug" or "shellshock ". This vulnerability allows attackers to execute code in the same way as they do in shell, which opens the door for various attacks. What's worse, this vulnerabili

In April 9, TechCrunch, a tech blog website, reported that OpenSSL, a security protocol used by many enterprises and services to encrypt data, had a vulnerability in the past two years, hackers can exploit this vulnerability to steal 64 KB data from the server memory. The 64 KB data volume is not large, but hackers can exploit this vulnerability repeatedly to steal data multiple times and obtain users' encryption keys to decrypt sensitive data. Even worse, even if the vulnerability is fixed,

immediately after the Shell is called. The severity of the Shell Cracking vulnerability is defined as 10 (highest). In April this year, the OpenSSL heartbleed vulnerability was only 5! Why is this vulnerability so popular? 1. The vulnerability has a wide range of impact and has been present for a long time. Bash, a Unix shell. The first official version was released in 1989. It was originally intended to be used on the GNU operating system, but can r
