CVE:CVE-2016-6302
CNNVD:CNNVD-201608-449
OpenSSL是OpenSSL团队开发的一个开源的能够实现安全套接层（SSL v2/v3）和安全传输层（TLS v1）协议的通用加密库，它支持多种加密算法，包括对称密码、哈希算法、安全散列算法等。
OpenSSL 1.0.2h及之前的版本中的ssl/t1_lib.c文件中的‘tls_decrypt_ticket’函数存在安全漏洞，该漏洞源于程序验证ticket长度时，没有设置HMAC的大小值。远程攻击者可利用该漏洞造成拒绝服务。
solution:Upgrade openssl openssl to a higher version than 1.0.1,1.0.1a,1.0.1b,1.0.1c,1.0.1d,1.0.1e,1.0.1f,1.0.1g,1.0.1h,1.0.1i,1.0.1j,1.0.1k,1.0.1l,1.0.1m,1.0.1n,1.0.1o,1.0.1p,1.0.1q,1.0.1r,1.0.1s,1.0.1t,1.0.2,1.0.2a,1.0.2b,1.0.2c,1.0.2d,1.0.2e,1.0.2f,1.0.2g,1.0.2h,and avoid the version 1.0.1,1.0.1a,1.0.1b,1.0.1c,1.0.1d,1.0.1e,1.0.1f,1.0.1g,1.0.1h,1.0.1i,1.0.1j,1.0.1k,1.0.1l,1.0.1m,1.0.1n,1.0.1o,1.0.1p,1.0.1q,1.0.1r,1.0.1s,1.0.1t,1.0.2,1.0.2a,1.0.2b,1.0.2c,1.0.2d,1.0.2e,1.0.2f,1.0.2g,1.0.2h; Upgrade oracle linux to a higher version than 6,7,and avoid the version 6,7; Upgrade oracle solaris to a higher version than 10,11.3,and avoid the version 10,11.3
