A fix is available — apply it.

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.
