Vulnerability Title
Angular: Denial of Service (DoS) via OOM in Date Formatting (formatDate)
Source: CVE Program / CVE List V5
Vulnerability Description
Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 22.0.1, 21.2.17, and 20.3.25, a Denial of Service (DoS) vulnerability exists in the @angular/common package of the Angular framework. The formatDate function, which is also utilized by the standard Angular DatePipe, does not properly limit or validate the length of the format parameter. When parsing a maliciously crafted, excessively long date format string (e.g., a repeating pattern or very large string), the internal parser splits the string iteratively using a regular expression loop. This results in uncontrolled resource consumption (high CPU utilization and excessive memory allocations), leading to a Denial of Service (DoS). This vulnerability is fixed in 22.0.1, 21.2.17, and 20.3.25.

Vulnerability Description
Angular是Angular组织开源的一个开发平台。用于使用 Typescript / JavaScript 和其他语言构建移动和桌面 Web 应用程序。 Angular存在资源管理错误漏洞，该漏洞源于@angular/common包中的formatDate函数未正确限制或验证format参数的长度，导致解析恶意构造的超长日期格式字符串时，内部解析器通过正则表达式循环迭代拆分字符串，造成不受控的资源消耗（高CPU利用率和大量内存分配），从而导致拒绝服务。以下版本受到影响：22.0.1之前版本、21.2.
