漏洞描述
中文描述:
Node.js是Node.js开源的一个开源、跨平台的 JavaScript 运行时环境。 Node.js存在安全漏洞，该漏洞源于TLS错误处理存在缺陷，当使用pskCallback或ALPNCallback时，远程攻击者可能使TLS服务器崩溃或耗尽资源，导致拒绝服务。
英文描述:
A flaw in Node.js TLS error handling allows remote attackers to crash or exhaust resources of a TLS server when `pskCallback` or `ALPNCallback` are in use. Synchronous exceptions thrown during these callbacks bypass standard TLS error handling paths (tlsClientError and error), causing either immediate process termination or silent file descriptor leaks that eventually lead to denial of service. Because these callbacks process attacker-controlled input during the TLS handshake, a remote client can repeatedly trigger the issue. This vulnerability affects TLS servers using PSK or ALPN callbacks across Node.js versions where these callbacks throw without being safely wrapped.
