Title: OpenSSL PKCS7_dataDecode函数拒绝服务漏洞
Description:
OpenSSL是一种开放源码的SSL实现，用来实现网络通信的高强度加密，现在被广泛地用于各种网络应用程序中。
OpenSSL的crypto/pkcs7/pk7_doit.c文件中的‘PKCS7_dataDecode’函数存在安全漏洞。远程攻击者利用该漏洞可通过畸形的PKCS#7二进制大对象（使用ASN.1编码并缺少内部EncryptedContent数据）发起拒绝服务（空指针逆向引用和应用程序崩溃）。
Severity: 中
Patch Name: OpenSSL PKCS7_dataDecode函数拒绝服务漏洞的补丁
