漏洞描述
中文描述:
Mozilla Network Security Services（NSS）是美国Mozilla基金会的一个函数库（网络安全服务库）。该产品可跨平台提供SSL、S/MIME和其他Internet安全标准支持。 Mozilla Network Security Services（NSS）中的 verifies certificates 存在缓冲区错误漏洞，该漏洞源于在NSS验证证书的方式中存在缺陷。攻击者可通过使用NSS编译的客户端应用程序发起SSL TLS连接来触发漏洞。
英文描述:
NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
