The Heartbleed vulnerability is still not fixed on more than 0.3 million servers. Message name from neowin: Unfortunately, this huge security vulnerability seems to have been forgotten too quickly. According to the latest report from Errata Security blog, more than 0.3 million servers are still using the affected OpenSSL version, which completely exposes the server to the Heartbleed vulnerability.

"The OpenSUSE community received a report about the bug that the IronPort SMTP server encountered an exception block due to the recent modification to the padding extension code due to the OpenSSL heartbleed vulnerability. OpenSSL 1.0.1g not only fixes the heartbleed vulnerability, but also adds some modifications to the padding extension: # Define TLSEXT_TYPE_padding 21 This directly causes an SSL Link e

Linux security vulnerability exposure Bash is more serious than heartbleed September 25 message: a Linux security vulnerability that is more serious than "heartbleed" was found, although no attack by this vulnerability has been found, but a lower operating threshold than "heartbleed" makes it more risky than the former. Bash is a software used to control Linux

Linux's most serious vulnerabilities are more dangerous than "heartbleed" According to foreign media reports, network security experts warned on Wednesday that a frequently-used section "Bash" in open-source software Linux has recently discovered a security vulnerability, its threat to computer users may exceed the "Heartbleed" vulnerability in April this year. Bash is a software used to control Linux com

Recently, the openssl (heartbleed) vulnerability is quite popular. It seems that some people on Weibo have said there are not many dangers in the past few days. However, according to the test, it is found that the damage is still relatively large. So I found a site and used a for loop to capture 100 files in batches. It took about 10 minutes to complete the process. There were about 10 accounts and passwords to search for. Basically, I could log on to

Search openssl heatbleed on the Internet to view tens of thousands of related content. Not only is online banking affected, but many security links encrypted through openssl have certain risks. Therefore, it is best to upgrade all its openssl as soon as possible. For example, the openssl version of The Redhat system is 0.9.8, and non-registered users cannot automatically upgrade to the latest version 1.0.1g through yum. However, we can use the source code for manual updates without the need to

Bash security vulnerabilities are more serious than heartbleed attacks. RedHat finds a computer software system vulnerability named Shellshock (or Bash Bug), which is no less serious than the "heartbleed" vulnerability in OpenSSL software. It is estimated that this vulnerability may affect the normal operation of more than 50 thousand computer devices. Researchers found the shellshock vulnerability in the

"Heartbleed" is called one of the most serious security vulnerabilities in the history of the Internet. It affects a large number of frequently-used websites and services, including Gmail, which many people use every day, users' passwords and credit cards may be easily disclosed.
