Technical description

This affects versions of the package angular from 1.3.0; versions of the package angularjs from 1.3.0. A regular expression used to split the value of the ng-srcset directive is vulnerable to super-linear runtime due to backtracking. With large carefully-crafted input, this can result in catastrophic backtracking and cause a denial of service. **Note:** This package is EOL and will not receive any updates to address this issue. Users should migrate to [@angular/core](https://www.npmjs.com/package/@angular/core).

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
