Microsoft Research JavaScript Cryptography Library是美国微软（Microsoft）公司的一款JavaScript加密库。 Microsoft Research JavaScript Cryptography Library V1.4版本中Elliptic Curve Cryptography的实现存在安全漏洞。攻击者可利用该漏洞获取敏感信息或创建无效的ECDSA签名（会被认定为有效）。
英文描述:
A Security Feature Bypass vulnerability exists in the MSR JavaScript Cryptography Library that is caused by multiple bugs in the library’s Elliptic Curve Cryptography (ECC) implementation.An attacker could potentially abuse these bugs to learn information about a server’s private ECC key (a key leakage attack) or craft an invalid ECDSA signature that nevertheless passes as valid.The security update addresses the vulnerability by fixing the bugs disclosed in the ECC implementation, aka 'MSR JavaScript Cryptography Library Security Feature Bypass Vulnerability'.
