CVE-2022-41724— Panic on large handshake records in crypto/tls

Quick assessment

Affected
Go standard library crypto/tls
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Google Golang是美国谷歌（Google）公司的一种静态强类型、编译型语言。Go的语法接近C语言，但对于变量的声明有所不同。Go支持垃圾回收功能。Go的并行模型是以东尼·霍尔的通信顺序进程（CSP）为基础，采取类似模型的其他语言包括Occam和Limbo，但它也具有Pi运算的特征，比如通道传输。在1.8版本中开放插件（Plugin）的支持，这意味着现在能从Go中动态加载部分函数。 Google Golang 存在资源管理错误漏洞。攻击者利用该漏洞导致服务器和客户端在尝试构建响应时死机。

Vulnerability Title
Panic on large handshake records in crypto/tls
Source: CVE Program / CVE List V5
Vulnerability Description
Large handshake records may cause panics in crypto/tls. Both clients and servers may send large TLS handshake records which cause servers and clients, respectively, to panic when attempting to construct responses. This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client certificates (by setting Config.ClientAuth >= RequestClientCert).
