CVE-2019-1549利用情况
暂无补丁情况
官方补丁披露时间
2019-09-11漏洞描述
OpenSSL 1.1.1引入了重写的随机数生成器（RNG）。旨在在fork（）系统调用的情况下提供保护，以确保父进程和子进程不会共享相同的RNG状态。但是，默认情况下未使用此保护。此问题的部分缓解措施是，高精度计时器的输出被混入RNG状态，因此父子进程共享状态的可能性大大降低。如果应用程序已经使用OPENSSL_INIT_ATFORK显式调用OPENSSL_init_crypto（），则根本不会发生此问题。在OpenSSL 1.1.1d（受1.1.1-1.1.1c影响）中已修复。解决建议
目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载：https://www.oracle.com/technetwork/security-advisory/cpuoct2019-5072832.html
