CVE-2024-21490

An Inefficient Regular Expression Complexity vulnerability was found in NodeJS Angular. A regular expression used to split the value of the ng-srcset directive is vulnerable to super-linear runtime due to backtracking, leading to denial of service.

The vulnerability in the Angular package, has been categorized as having a moderate severity rather than being labeled as important due to several factors. While the regular expression used for splitting the value of the ng-srcset directive is susceptible to super-linear runtime caused by backtracking, the practical exploitation of this vulnerability requires a large, carefully-crafted input. This input, which triggers catastrophic backtracking and potential denial of service, would not be easily achievable in typical use cases. Additionally, the affected package, Angular 1.3.0, is already designated as End of Life (EOL) and is not receiving updates, limiting its relevance to current development practices.

Red Hat Enterprise Linux is not affected as its not shipping the vulnerable code.
