Summary
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.
A remote attacker could exploit a Denial of Service (DoS) vulnerability in the `formatDate` function, which is also used by the Angular DatePipe, by providing an excessively long and maliciously crafted date format string. A flaw was found in Angular's @angular/common DatePipe.
A crafted date format string can cause excessive CPU consumption, resulting in a denial of service. Red Hat Integration Service Registry includes @angular/common in its UI components and is affected by this vulnerability.

Mitigation checklist
- Validate and sanitize user-supplied date format strings before passing them to Angular's DatePipe. Implement request rate limiting and timeouts on web application endpoints to limit the impact of malicious requests.
