! 1 0 December, the security personnel also discovered the Heartbleed vulnerability in the trail, the use of the vulnerability an attacker can obtain the password of the user and convincing the user to visit a forged website. myhack58 Encyclopedia The Heartbleed Vulnerability, CVE-2 0 1 4-0 1 6 0, the CNNVD-2 0 1 4 0 4-0 7 3, is OpenSSL the one major security vulnerability, 2 0 1 4 年 4 月 7, by foreign hackers exposure. The vulnerability can allow an attacker to get on the server 64K memory content data. Due to the use of the OpenSSL source code of the website a huge number, and therefore the vulnerability impact is very serious. OpenSSL is a powerful Secure Sockets Layer password database, to include major cryptographic algorithms, commonly used key and certificate package management functions and SSL Protocol, and provides a wealth of applications for testing or other purposes. Vulnerability details The vulnerability exists in OpenSSL, you can leak the server's memory content, which contains a large number of hosting data and other sensitive information such as usernames, passwords and credit card numbers, etc. In addition, the attacker can also copy a server's digital keys, and then fake the server or to decrypt communications.

In addition, its security team is the rest of the site to achieve the repair. However, Yahoo also did not provide users with the relevant security recommendations.
